I'm going to assume that you've installed Boot Camp and are running Windows 7 along with Snow Leopard on the same machine. While the Boot Camp drivers allow you to read HFS+ partitions, they do not allow you to write to them. Therefore, one approach is to use MacDrive, which enables read/write support for HFS+ partitions in Windows. Using MacDrive, here are some instructions for setting it up such that you can access your OS X iTunes library from Windows.
Another option is to store the entire library on a third partition or an external drive, and have both OS X and Windows point to it.
