Is it possible to use a joypad as a mouse?

I've got a usb joypad and i was wondering if it was possible to set it as my computers mouse. can it be done?

 

It is possible with a program called joy to key. The program lets you set any joystick button, analog, or plus pad to a mouse or keyboard function. It can be used for buttons and moving the mouse.
