Try one of these: http://download.cnet.com/1770-20_4-0.html?query=partition+manager&platformSelect=Windows&tag=srch%3Ba&searchtype=downloads&filterName=platform%3DWindows&filter=platform%3DWindows

first of all, BACKUP your data before making any changes to your drive.
cleanup your drive and remove any unwanted data. defragment your hard disk. now you can resize it to make room for a second partition. You can use a tool like parted. It comes standard with Ubuntu live cds.
