Yes, of course.

Depends on what UI toolkit you're using.  For PyObjC/Cocoa, here's  
Apple's documentation:
http://developer.apple.com/documentation/Cocoa/Conceptual/DragandDrop/

If it's just a droplet with no UI (a command line tool that takes  
filenames on sys.argv), you can get away with py2app's argv_emulation  
option.
