software sugguestions for using as on a touchscreen pc

I recently purchased a usbuirt and I have been playing around with quite a few different software packages. None of them seem to get me where I want to go. I have a touchscreen winxp pc in my house that I want to run "some software" app on that will allow me to put some buttons on the screen to control all sorts of AV equipment. I have looked at Girder, Housebot, and Homeseer. Housebot was the closest to what I want, but it was very hard to "create good looking buttons" and seemed very cumbersome to me. I waded throught it for about 4 days before deciding it wasn't the ideal solution. Most of these packages seem to be designed to control your pc, not used for your pc to control AV equip. I really want a pronto like package that runs on a standard pc. Any ideas??
