Hi Lauren,
So your ipod is in HFS+ format and you want to convert it to FAT 32 to work with Windows?
From all accounts,
AFAIK, it is not an easy process! - There are articles on the internet such as
THIS ONE but I would read very carefully before you attempt this.
It may be easier to put a Linux partition your windows machine and use your ipod that way, or maybe someone knows of an easy way to do this.
May I ask why your only alternative is a PC as opposed to a Mac? (Just curious, you don't need to explain of course

)
