Transform a Java application into a web app

We developed a desktop java application which represents a card game called "Tarneeb" the game is kinda similar to Bridge. Anyway, the game is done and finished but we need to transform it into a web application to be run from the browser, It should be a multi-player web app where a client can make a new room and people join to make a new game. Full java 6 code will be supplied with documentation and comments on each piece. We are a team of young java learners and we will guide you in the process of the transform in case anything isn't understood fully. Attached is a screen-shot of the game.
