Emulater type program?

[inform880]

Hi,

I want to make a program for my (way younger)brother that only lets him open up programs that my parents let him. I have come up with several ideas, but they all are either too advanced or just don't work.

The ideas I have come up with:
-new OS.(Nope!)
-an emulator type thing.(maybe)
-somehow using the createprocess() command with an Allegro 5 program that is full screen.(preferable)

Thanks for any ideas!
