I wrote a mail on the same topic to the libgit2@librelist.org mailinglist, because I got interested in the same project (although I will not be a GSoC student).

I guess a lot can be copied from Git itself. Actually builtin/rev-list.c consists mostly of command line arguments parsing methods, and outputting functions. The key is to parse what you want to know and ask libgit2 to provide the info. If libgit2 has implemented the basic functionality that is needed, the rest would be relatively simple.

AFAICS, current git is a single binary on Windows already.

Why not CMake which is also used for libgit2 ?

I already wrote a CMakeLists file for your git2 app.

As you know, this project can be possibly fulfilled by a GSoC student (either you or someone else). Maybe people are awaiting this before diving into the project.
