Yes.

Short answer: use "pythonw" not "python"

Long anser: The OS X Cocoa WindowServer (I'm paraphrasing the proper 
terms, which I'm sure are slightly different) requires something like 
any application that wants to open a GUI window must be clicked or 
equivalent.  Since that's not the way python generally works, pythonw 
for OS X was modified to do some black magic (LaunchServices??) to get 
around this requirement.  This stuff is not in the normal python 
executable. For this reason, I have my trusty ipython shell using 
pythonw on OS X.  There doesn't seem to be any problem running non-Tk 
apps with pythonw.

FYI, pygame has something that will print a complaint if it's not run 
with pythonw.  We could look under the hood and figure out how it's 
done there...
