Launch an application in an existing Form?

Hi,

I am sending this question on behalf of my son (age 17) who is writing his
first .Net program using C# 2.0.

The program is a kind of framework that lets you define, position, and size
windows that contain 'appliances'. One appliance can be a website, another
an instant messenger program, yet another a game.

The question is: is it possible to launch an application to run in an
existing WinForms window (Form)? Or maybe launch an application and after
it's loaded set its 'Parent' property? The last option will require some
low level GDI32 or Kernel32 hacking, I guess.

Thanks in advance,
Paul ten Brink
