Can i use a PC games controller as a mouse or pointing device?

YES! Download a copy of JoyToKey and you can set up to sixteen gamepads or joystick to act as a the ivories (ctrl, space, etc) or mouse.
It depends if your controller supports it. Theoretically it will work. But I guess a program is need to identify it as a pointing device and configure the buttons equivalent to the mouse. check the manufacter's website for software downloads
yes you can download a fun program call SuperJoyMouse from http://www.download.com/superjoymouse/30... this is a time limited trial(10 minutes),but the full license is singular $19(around lb8),so it will be worth it in the longrun

other programs include MouseHook 1.1.0-5 alpha(http://www.download.com/mousehook/3000-2... allows you to customize your current mouse and Nostromo Array Programming Software 2.6(http://www.download.com/nostromo-array-p... allows you to customize your input devices to suit your personal wants

hope this helps

moral luck mate!
