The examples and documentation on the PyObjc website should get you  
going as far as actual code is concerned.  Development using Xcode  
isn't documented very well (or at all) at the moment, mostly because I  
don't use Xcode a lot myself.

For simple applications it you can just add all your Python files to  
an Xcode project that's started from one of the Python Cocoa templates  
that ship with Xcode. Don't forget to import all modules that define  
classes that are used by your NIB files (the "main.py" file seems  a  
great place to do that), otherwise the modules won't be loaded and  
Cocoa won't see your classes.

Things get a little messy when you have dependencies on 3th party  
libraries, Xcode won't automaticly copy those into your .app bundle  
and you'll have to add a custom shell-script step to your Xcode  
project to do that for you.  It should be possible to create a tool  
based on py2app that does this for you, but AFAIK nobody has looked  
into that yet.
