BTW you *must* have a Python installation on your Windows machine in order for Python to find necessary library files. As above you can download Python 2.7.4 from http://www.python.org.
Your PYTHONPATH environment variable on Windows should look something like this:
C:Python27-x86Lib;C:Python27-x86libs;C:Python27-x86DLLs;%GLADE_HOME%
