Then maybe you should stop being lazy and contact corsica :P(Windows packet editor was written in microsoft visual c++) Olly is pro open source so maybe you could drop corsica an email for some help. BTW: You probably won't get the WPE source but, Olly will most likely try to help your n00bish little self.

EDIT: Those websites for learning to use wpe and other useful tools are http://fly.to/mtc (Windows Packet editor's Home) and http://www.gamehacking.com (Has good tutorials and other network tools which maybe useful)
