If you are talking about about creating a GUI and having be able to
run using different GUI libraries like Tkinter, wxPython, wxgtk, ect.
You could look into Dabo(http://dabodev.com/). It is designed so that
you can design your GUI and have it run with what ever GUI library you
want(only wxPython is supported at the moment. And I think that
Tkinter works somewhat.)
