WxPython versus Tkinter.

Python cares *a lot* about maintaining backward compatibiilty between
all major versions.
This is so true that I managed to use a unique code base for pyftpdlib
which supports python from 2.3 to 2.7.
Same for psutil which covers versions from 2.4 to 3.2 by using a
unique code base!

Usually the differences between one version and another rely on *new
features* only.
One might decide to target a module only for a certain version of the
2.x serie because that certain version introduced a new functionnality
which was not available before (silly example
http://docs.python.org/library/os.html#os.initgroups ).
All the other functionnalities are likely to remain the same and fully
backward compatible.

> py2exe-0.6.9.win32-py2.6.exe
> py2exe-0.6.9.win32-py2.7.exe

That's a different story: those are pre-compiled binaries which are
generated from a *unique* source code which support all those
versions.
If you have a compiler you can install pywin32 extension by using any
Python version.
