I had to do the same thing.

Basically what I did was mimick the way cutesoft did their's by copying the code-behind (and logic) in the Lobbies.aspx and LobbyItem.aspx files. I created my own pages and controls in the exact same way they did theirs.  These can be found in the 'CuteSoft_Client\CuteChat\Admin' directory.

I basically just wrote to the CuteChatLobby table myself, that creates a chat room. I would think that if you wanted to destroy it afterwards  you would just remove the row from that table based on the LobbyId.

Hope that helps a little.
