Well, you might want to read up on some beginners guide for python? It's 
up to you, of course, but usually before starting with numpy (which 
extends python), it is advised to have at least some basic python 
understanding... Googling will give you plenty of good resources, if 
you'd like to.

Then, for the sake of helping you further anyway:
you'll have to mind the significance of paths (=directories or folders 
in windows speak I think). The folder you're currently in, will restrict 
what you find when typing commands. If you need to reference something 
from a different folder, you'll need to explicitly specify that.

To build numpy, you'll need to be in the numpy source folder (the numpy 
you extracted from svn). But if you're there, simply typing 'python' or 
'python.exe' will probably not work because 'python.exe' is in a 
different folder (c:\Python31). You could go into that folder, but then 
you would not be able to find numpy's setup.py script. Best way to solve 
that: make sure you're in the numpy folder, and type something like: 
'c:\Python31\python.exe setup.py build'. That should get you started at 

However, if I'm allowed to give you some unaskedfor advice: this might 
become lots easier if you make sure you're at least a bit comfortable 
with 1) the windows command prompt, 2) python, and 3) building python 
stuff from svn source checkouts. No offence meant. But you sound as you 
feel a lot more comfortable with pre-built packages compared to building 
yourself from source on windows...

Good luck anyway!
