I need a desktop for kids

I was wondering if anyone has created or will make a desktopx for kids. For example blocks them from accessing the majority of configs and programs but leaves them with icons that let them access internet, my documents, wordpad, and a couple other basic needs. Please reply if you know of any desktops or will offer to make one. I am trying to create one right now, but its still at work. Here it is if you want to add on to it  http://www.freewebs.com/sum3umm/The%20Guest%20Desktop.desktop
