Actually you might prefer to just use the LyX dependencies package that we provide for Windows developers, it contains Qt. I paste here the relevant part of our 'INSTALL.Win32':
6 Install the dependencies Download ftp://ftp.lyx.org/pub/lyx/contrib/lyx-windows-deps-msvc-qt4.zip and extract in the root directory of your LyX files (so you will get a directory called lyx-windows-deps-msvc-qt4 next to the other directories like src, development etc.).
I also attach the complete file, you might find some interesting items WRT compiling with MSVC.

Compiling LyX 1.5 for Win32 ===========================
LyX 1.5 can be compiled with Microsoft Visual C++ 2005 (recommended) or MinGW.
Compiling with MSVC 2005 ========================
1 Install MSVC 2005 SP1
If you don't have MSVC 2005 installed, download and install the free
Express edition from http://msdn.microsoft.com/vstudio/express/visualc/
From this page you should also download and install Service Pack 1.
A hotfix needs to be installed because of a bug in the compiler.
Search for VS80sp1-KB930859-X86-ENU.exe on Google and install it.
2 Install the Windows Platform SDK
see: http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
(You don't need to install the IIS, MDAC, and Tablet PC SDK that are
delivered with the Platform SDK.)
3 Configure MSVC
Follow exactly the steps of
http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
In Step 3 follow also the things noted as alternative.
(If you later get an error message that "windows.h" cannot be found,
create the global Windows environment variables "INCLUDE" and "LIB".
INCLUDE contains the paths to the "include" folders of the installed
platform SDK and of MSVC. LIB contains the corresponding "lib" folders.)
4 Install Python
Get the latest Python 2.5 version at
http://www.python.org/download/releases/2.5/
Install in C:\Python25 and add this directory to the PATH environment
variable (Start > Settings > Control Panel > System > Advanced >
Environment Variables).
5 Install SCons
Download and install SCons 0.96.92 (or newer, but not 0.96.1) from http://www.scons.org/download.php
6 Install the dependencies
Download ftp://ftp.lyx.org/pub/lyx/contrib/lyx-windows-deps-msvc-qt4.zip
and extract in the root directory of your LyX files (so you will get
a directory called lyx-windows-deps-msvc-qt4 next to the other directories
like src, development etc.).
7 Compile
From MS Visual Studio command prompt (not the regular cmd.exe),
run
> cd <lyx root directory>\development\Win32\packaging
> build_msvc.bat
8 First start of LyX
To start the just compiled lyx.exe, it is necessary to copy the following
files to the folder where the just compiled "lyx.exe" is:
Aiksaurus.dll
aspell.dll
iconv.dll
intl.dll
Microsoft.VC80.CRT.manifest
msvcp80.dll
msvcr80.dll
QtCore4.dll
QtGui4.dll
msvcp80.dll and msvcr80.dll are the C Runtime and C++ libraries
supplied with MSVC 2005. They are freely redistributable.
See http://msdn2.microsoft.com/en-us/library/8kche8ah(VS.80).aspx
for details.
All of the other .dlls above and the lyx executable are compiled
from code released under the GPL which states (section 3) that
GPL software may be linked against system files such as msvcp80.dll
and msvcr80.dll.
Compiling with MinGW ====================
These instructions allow you to create a basic LyX build with MinGW.
To be able to use all LyX features, compiling with MSVC 2005 is recommended.
Creating an installer for MinGW builds is no longer supported.
1 Install MinGW, and all the gcc-related stuff, and win32api.
2 download qt-win-opensource-4.x.x-mingw.exe and install to c:\qt\4.2.2.
3 install python and scons as instructed above. Set $path for python
to make your life a bit easier.
4 Check out lyx svn to c:\lyx-devel\lyx-1.5.x
5 Download zlib binaries and developer files (zlib-1.2.3-bin.zip and
zlib-1.2.3-lib.zip) from http://gnuwin32.sourceforge.net/packages/zlib.htm
libiconv from http://gnuwin32.sourceforge.net/packages/libiconv.htm
gettext from http://gnuwin32.sourceforge.net/packages/gettext.htm
unpack all of them to the same directory c:\lyx-devel\mingw_deps.
6 start a command window, run commands:
$ cd c:\lyx-devel\lyx-1.5.x
$ scons -f development\scons\SConstruct \
extra_lib_path=..\mingw_deps\lib \
extra_inc_path=..\mingw_deps\include \
extra_bin_path=..\mingw_deps\bin \
qt_dir=c:\qt\4.2.2 \
DESTDIR=..\lyx-1.5-install \
install
Creating the Installer ======================
To create an installer with LyX and all related components, download
and install the latest NSIS from http://nsis.sourceforge.net
Open development\Win32\packaging\installer\setttings.user.nsh and modify
the settings depending on your build environment.
Finally, go to development\Win32\packaging\installer
(in a normal Windows Explorer), right-click on lyx.nsi and click
"Compile NSIS Script".
You can also use the installer target of scons. Namely, use a command like
$ scons -f development\scons\SConscript installer
This will create $BUILDDIR\lyx-version-timestamp-Installer.exe for a devel version,
and $BUILDDIR\lyx-version-Install.exe for a released version of lyx.
If you also want to generate bundled installer, download
lyx-windows-bundle-deps.zip from http://www.lyx.org/~bpeng, unpack
to lyx-windows-bundle-deps under the top source directory, and run
$ scons -f development\scons\SConstruct installer bundle=1
If you prefer to use another directory, you can use option bundle_dir like
$ scons -f development\scons\SConstruct installer bundle=1 bundle_dir=c:\bundle
