It's probably not really what you're looking for, but I've been wrapping GapiDraw in Python for Symbian on the P800/P900. I'm only using a limited subset of the functionality right now, but I have Python bindings for the same API in C++/Fltk on Python running under Linux, and I'm confident that it would also happily work under OS X.
I'm hoping to relase the basic wrapping functionality as open source. The main thing I need to work on is pen response for Symbian.
One warning: This code is not very clean, and is not ready for end-user use. Python is an EXE, and currently requires an external keyboard to work...
