One step at a time.

The most common reason for IDLE not running on Windows is that the
user installed Ruby.  The Ruby Windows installer is a bad citizen,
setting environment variables that prevent other apps from using Tk. 
Did you install Ruby?

Open a DOS box, cd to your Python directory, and try this:

C:\Python23>python
Python 2.3.4 (#53, May 25 2004, 21:17:02) [MSC v.1200 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>> Tkinter._test()

What happens?
