I find wxPython to pro fill my GUI needs from python in a pretty good way. To show off it's capabilities - I am building a GUI editor and it currently converts from windows forms (visual studio c# forms) to wxPython code. When I started programming this editor I thought I'd have major incompatibility problems, thinking wxPython is extremely weaker than the windows forms. However, coding the conversion between the two proved wxPython to be highly capable. BTW, this GUI editor can be found here: http://farpy.holev.com
I believe this also provides an answer to gsteff's post about not having a normal GUI editor. -- http://mail.python.org/mailman/listinfo/python-list
