I am using Python 2.3.3 on an Mac OS9 system. I am looking for a build of Python 2.3.3+ with a built in GUI, since Tk is missing. One day I hope to upgrade to a new Mac with OSX on it, so a GUI that is available on OS9 and OSX is preferable. I don't want to write my GUI code from scratch if I ever manage to upgrade. Any suggestions?
