heh, sorry.
I was talking about programming language. Here's what I suggest you do if you're interested in making a program that does what you said.
Learn C#.NET (it's a programming langaueg), then search google and msdn for three things
1. How to Create/Start Processes
2. How to Kill/Close Processes
3. The ProcessInfo and Process Class
Granted, it may be hard to wrap your head around since you're new to it, but if you're serious about learning you'll get the hang of it.
