Project-controlling PC through Cellphone..

hi.. i am in last yr..Diploma.. i have a project idea-Controlling PC via Cellphone.. The project i need to implement is simple where via Wi-fi/ bluetooth i can control my PC.. without taking the screenshots on mobile phone. Simply without using Internet/gprs activated on cell or using IP address for accessing the server-to be installed on desktop PC(as per the references i have searched) i should be able to control the desktop PC.. Is it possible to code the entire in java?? or does java supports networking??
i also need to use J2ME for d application on cellphone..

Plzz help.. give me some idea abt actual implementation.. also the requirements for the same..

Thank you...
