Core3R 0 Newbie Poster

Hi to all. I am planning a program that controls the other Computer's basic functions (shutdown, reboot, sleep, wake,). It is somewhat similar to Handycafe program which is used for Cybercafes. My point is that i want to make my own configured program that only accepts a passcode then automatically search for the available pc from the clients. Im gonna attach a file which i made. It is just a concept design and i want your idea if it is possible to be made or not. If it is possible,, then please help me.

Anyone is very welcome to make a comment.
