I think that's perhaps an understatement. <grin>

I'm pretty sure the tutorial didn't instruct you to actually use the
shell to write GUI (or any kind of) applications... (By the way, you
didn't mention what tutorial you're using?)

Yes, well, it's a bad idea, and the downsides you mention is true of
writing any Python application, not just GUI ones.  You should use the
shell to experiment, test, peform introspection, read documentation,
etc. etc, not to actually develop your applications... that's what
editors and IDE's are for.

TkInter apps can sometimes not play nice with Idle when run from
within Idle for various reasons which I've now forgotten (partly
because Idle is itself written in TkInter I think), but I seem to also
vaguely recall that this is somewhat less of a problem nowadays than
it used to be and/or the issues can be avoided with a bit of care.
(I'm sure the others on the list will correct me if I'm imagining
things and/or elaborate on this.)  So, if your app is simple, and
certainly while you're learning you might want to use Idle despite
what tutorial says. At worst, you can avoid issues by simply running
your application manually e.g. apart from Idle. (Notwithstanding your
next point.)

Well when done correctly it should work.  It's impossible to tell
without more information about what's really going on why it's "doing
nothing."  There may be a problem with your program, there might be a
problem with your Python setup, there may be a problem with your
operating system environment, etc. etc.  Anyway, if you open your .pyw
file with say Windows notepad or any other text editor (or, indeed,
Idle), what does it contain?

What version of Python?  I recommend the Activestate distribution of
Python on Windows these days as their installer does several
convenience steps automatically that the official Python distributions
do not do and provides several tools useful on Windows as well.  You
might have a look at it/switch if you're not using it yet:

Hope that helps,
