Tabbed Programs

Alright. Crazy/lazy idea time.

I need to know, would it be possible to program an application that is basically a shell for several programs.

For example, web browsers like IE, FF and Opera all support tabbing for websites. Would it be possible to host several programs (without having access to their source) in a single "shell" without them showing up on the start bar.

I would use this for making games, recording music, designing pictures. I'd have one program open containing RPGMaker, Idraw, Photoshop, Irfanview and Paint and another containing my browser.

That'd be cool. Sound possible?
