Do other Python GUI toolkits require this?

This appears more or less unique to Objective C. It looks that with 
PyObjC, you have to interact with the Objective C runtime to manage 
memory. This is not required, thankfully, with any other GUI tookits 
I've seen.

I think the main difference is that PyObjC is not a GUI toolkit per se, 
but is simply a means to make the Objective C runtime (and hence Cocoa) 
available via a python layer.
