Client-Server application with Java and MySQL Database

I need some one who knows how to develop java applications which can run properly in a networked environment with a central database, in this case (MySQL) - client-server applications. I have the databases for the applications already designed, and only need help to develop the applications and user interfaces on top. Either you can develop the applications or you can take me through the steps to do so, as I have java programming experience in desktop application using Netbeans IDE. A well guided explanation can actually suffice. Please contact me for more details.
