What is the best drag and drop GUI builder for wxPython? 
I've tried wxGLade, but I strongly dislike it.
If you are just starting out on GUI programming in Python I'll strongly recommend ditching wxPython for PySide/PyQt4. It has a simpler API and Qt-Designer is one of the best drag 'n' drop GUI designer I've used. Plus PySide/PyQt4 is well documented.
