OpenGL / DirectX GUI Overlay

If you've ever used Steam or Xfire, both of these have an in game overlay menu. How does one go about this in concept?

Well, looking at their SDK info, it seems they inject a DLL or something:

Xfire injects a .DLL into games it supports for a system called Xfire In-Game. This is used to enable keyboard intercepts and drawing intercepts for allowing users to send and receive messages while they are in a game.
