Building basic dialog in Windows?

[Fred]

Hi,

	I'd like to turn a command-line script into a Windows GUI app
using the native widgets so as to reduce the size of the binary (ie.
no QT, wxWidgets, et al.)

I came up with the following list of tools to access the Win32 API:

- PythonWin (MFC) http://www.python.org/windows/pythonwin/
- ctypes http://starship.python.net/crew/theller/ctypes/
- EasyDialogs for Windows
http://www.averdevelopment.com/python/EasyDialogs.html
- DynWin http://www.nightmare.com/~rushing/dynwin/
- sdk32 - Partial Python wrap of the Win32 Platform SDK
http://www.object-craft.com.au/projects/sdk32/

Does someone have a sample on how to display an OK/Cancel dialog with
a label + progress bar? Should I look at other tools?

Thank you
Fred.
