pythonw.exe is designed to let you run a python script without
an associated console window.

to make something appear on the screen, you must 1) pass
a script name to pythonw.exe, and 2) make sure that script
creates a window (usually by using Tkinter or any other UI

(you can get around (1) by using the extension ".pyw" instead
of ".py", and clicking on the pyw file.  the following excerpt from
o'reillys "python programming on win32" contains a little more info:


if you're just tinkering, use IDLE or fire up a command (MS-DOS)
window, and run the interpreter from there:

    c:\mydir> python


    c:\mydir> python
    PythonWare 2.2b1 on win32
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import mymodule
