I've been following this entire thread, and I'm afraid I have no clue
at all waht you mean by that last phrase "forcing the creation of GUI
elements for non-GUI-based programs".

In Windows the default for python applications is that they run in a
console session with stdin/stdout/stderr attached to a terminal
emulator.  The application itself may or may not create GUI windows on
its own -- that's independent of whether it's attached to a terminal
emulator or not.

Sure they do.  When you create a launcher item or menu item in most
desktops, there's a setting that says whether you want the program run
in a terminal window or not.  That's exactly the same thing you're
controlling under Windows when you set the filename to .py or .pyw.

No, we're not talking about whether apps invoke GUI functions or not.
That's completely orthogonal to the issue at hand.  We're talking
about whether desktop manager should run the program with
stdin/stdout/stderr connected to /dev/null or connected to a terminal
emulator.

The windows desktop determines that (like it determines other things)
by looking at the filename.  Other desktops generally have that
information associated with the icon/button/menu-entry, not with the
executable's filename.
