Server control panel (windows)

Hey there.

Here is the thing,
i run small Vps server for 3 gameservers,
on windows 2008

I want for some of my friends to have access to server control panel ( ftp - to change game server configs and start/stop - to refresh changes )

So what i need is very basic and simple server Control panel with option to make command lines for specific .exe, ftp access for users, and start/stop server.

I tried to google it, but i found only control panels for website hosting (mysql, php...) But again , i really need just command line access, ftp access, start/stop.
It would be nice if it is free.

Your help would be much appreciated !
