remote control for my desktop

Exams are coming fast.
    [/alert]

I am writing a remote control for my Linux desktop. What I want to do is:

1. control audio player            done
   
2. control video player
3. access movie database
   
4. control tv tuner
   
5. to look like a real remote control, with a LCD screen.
   

BTW, in gtk# method setFromFile can't be used in a image widget.
You can do something like this:
   Gdk.Pixbuf pix= new Gdk.Pixbuf("/tmp/muine/1.png");
   imgCoperta.Pixbuf= pix;
