Alternative Game Lobby

Im not sure if this is possible but I am wondering anyways. I wish to have a piece of software created for a game which will act as a chatroom and place to host games, it will serve as an independent piece of software which will allow people to play the game without the need of the original lobby and interface the game runs on. The software must be able to be distributed and used online, since this will be the 'peer to peer' connection that players will have with one another. I can supply a sample of a lobby which was created by someone else however was never fully implemented to allow users to play the game with eachother without the aid of the Online interface the game had itself. I am unsure as to what is required in terms of skills etc for this project, so please feel free to bid away, More details are available upon request.
