I wish to write a cross-platform application in Python. The question I have is this: How do I handle the Windows version? I'm going to use the PyObjC support built into Leopard's Xcode for the Mac OS X release. Should I use IronPython, wxPython, or some other Windows toolkit for Python development there? Also, I may decide to make a Linux version at some point - the big thing preventing me from doing that now is no easy way to test it.
