I dont think you are going to find someone else that has tested them all and can tell you which
one is best for you either.
A lot of them can probably deal with your requirements listed.
It depends on what version of python your using and what type of GUI
application you want to make and then it also comes down to personal preference.
Most replys to gui
advice will just be someones personal preferance.
This is a list of the most popular ones (which
is just my opinion not fact) for you to start looking at.http://kivy.org/http://wiki.python.org/moin/PyQthttp://www.pyside.org/http://wiki.python.org/moin/TkInterhttp://wiki.python.org/moin/WxPython
