Opening multiple programs asynchronously

Hi /prog/, I'm working on a networked program that has a server and clients.  Due to this, I often find it tedious to start the server and several clients to test something.  I'm looking for a simple easy way to write a program that opens the server and the clients for easy testing.  If I were on *nix it would write a simple C program with a couple forks(), but alas, I'm developing on windows and I don't know much about windows threading. Can someone help me out?

Make a C# program if you want; there set-up for executing is very easy and well-documented.
