Yes, of course.  Image.open('myapp.icns').save('myapp.png') will 
probably Just Work.

The easiest way would probably be to use IconFamily from PyObjC 
<http://homepage.mac.com/troy_stephens/software/objects/IconFamily/>.  
Carbon is always a pain in the ass, but the Icon Services functions may 
be wrapped (not sure?).  NSImage will load pngs and jpegs quickly and 
easily.
