Using Windows w/ 100% Open-Source Software?

XRayX asks: "I'm currently installing a Windows 98 PC and I'm trying to install just Open Source Software (except Windows and Drivers). Okay, there's Freeamp, GIMP, Mozilla, OpenDivX, VirtualDub, Audacity, Abiword, Tuxracer and FlaskMPEG for Windows; but I'm still missing some good Open Source Tools for Windows: a picture viewer and a GUI Zip-program. Can anyone help?" While an interesting thing to try, I don't think it will be as easy as it sounds. How many others of you have tried to pull this off and how successful were you?
