OS X doesn't know how to deal with such things, in general.  GUI
(Carbon/Cocoa) applications should be applications, or at least
packaged as such, otherwise a lot of stuff breaks.  For example, an
app needs an icon and a name in the dock, and in the menu bar; what if
someone chooses "Show in Finder"?  What kind of documents could the
script open?

None of these items can be synthesized without either Info.plist or
resource ('BNDL'/owner/'plst') based.  py2app is very simple to use,
and can produce small, self-contained script applications.  Or if you
just want a one-off thing for your own use, try pythonw, but realize
it's getting all this information from Python.app.

This is really no different from AppleScript - scripts must be saved
as applets before they can be double-clicked.  Otherwise, scripts
typically run in another application's context, for example that of
the Script Editor.  AppleScript explicitly prohibits use of the GUI
from the command line:

% osascript -e 'display dialog "foo"'
0:20: execution error: No user interaction allowed. (-1713)
