cross platform question GTK+vs.wxwidgets
I want to write GUI programs to run on at least linux and win32. Can Gtk+ run on win32 well? Must I learn wxwidgets to have cross platform support? I have seen great Gtk+ applications like Gaim run on Linux and win32, how much code change, if any, was needed?
Essentially I want suggestions on what toolkit to use. I have ruled out Qt and Motif for various reasons and I want an open source toolkit for sure. I also prefer C to C++ which is one reason I like Gtk+.
