I tend to build command-line tools and services. But when I need to
build something with a Mac UI I pull up Xcode and use the Cocoa-Python
template. Works like a charm -- but I believe it depends on the system
Python. By the way, if you need to do this, take a look at Hillegass'
book, COCOA PROGRAMMING FOR MAC OS X. And read Will Larson's great
series, starting with

Don't know, because I always use the "system" Python for non-Python-dev
coding. But I'm betting there are some dependencies in Xcode or the
Xcode templates which require the system Python.

Sure. But anything hard-coded can be overridden. The sources are just

Unless you're developing just for the Mac, I'd suggest using PyGUI or
wxPython or PyGTK or some such, and build applications (small 'a') with
that, instead of Cocoa.
That experience will port out of the Mac to other Unices and Windows.
