Adding second mointor & keyboard

[twswtn]

I want to add another mointor, keyboard and mouse to my existing Dell desktop computer. I have a wireless usb keyboard and mouse I was planning on using, but I do not know of a wireless mointor. Besides the mointer and cable, what else would be needed to add this second mointor and will all this work that I want to do?
Thanks
