Jython and Cocoa could work very nicely together! Apple has an 
equivalent Java API for its frameworks and I find it to be more
natural to use than anything pyobjc-like that I've seen so far,
one reason being that it doesn't result in plenty of underscores
and parantheses that seem to be needed for simulating Objective-
C's method signatures in Python.

Also, pyobjc development seems to be more or less stalled (?), so 
I've never been sure what to expect from that side in the not so
distant future.

I've added below some of the most simple test functions from my 
growing test suite just to give you an idea...
