Software Program for Broadband

I am looking for a coder to develop a software program, for novice PC users, who are experiencing problems with their broadband connection. My main aims is to have a really user friendly GUI that will ask the user a few questions to determine exactly what is wrong with their broadband and from that the program will check and configure different settings on the individual PC in order to resolve the issue. I am thinking this will be done through Java and the command line interface for such functions as telnet, ping, network connection status etc.. But if anyone has any other suggestions, I would be pleased to hear them. I have a Requirement Spec done out and will show to any coder upon request. ## Platform Windows XP
