Nice idea!  I suggest you use a spinbox instead of an entry though,
since that has up and down buttons, and allows you to restrict the
value to an integer.

You can put a trace on the associated variable and specify a function
to be called when the variable's value changes.  Grep for "trace add
variable" in gitk to see how it's done.
