I'm not sure what I'm looking for but there may be something on the mac developer site
http://developer.apple.com/

 I know you can use xcode and quartz to wrap python scripts into apps. Not sure if there's much in the way of documatation with the developer stuff that comes with the mac os install discs. think you can also combine python with automator scripts.

 I'll try and keep searching for you. I've done a few automator  scripts in the past but not really played with xcode or python
