It doesn't get any more cross-platform than Python ;)

Technically speaking, as long as you have Python, Qt-4.x ("x" will be defined 
by the newest Qt class/module/function that you'll be using from your code), 
and an accompanying PyQt4, you should be set. Of course, this is as long as 
you use only Python modules which are available on both platforms (e.g, using 
any GNOME-related Python package will render your code unexecutable on Windows 
IIRC).

This is one of the resources I used when I first ported PyGTK programs to 
Windows: http://www.py2exe.org/index.cgi/Py2exeAndPyGTK hope it's useful.

Glad to see it worked for you :)
