A wireless setup is not that much different than a wired setup. The only difference is obviously, no wires.
Get a wireless router. And you'll need wireless cards for each computer. If you get a router with ports, you can set it up by one computer, and use the ethernet port on that pc, and get a wireless card for the other computer. Here are basically what you'll need. These links are from walmart, so you can get them from the store. But as always, it's cheaper to get them online. From ebay, or a site I like,

This router does have 4 ports, so you would only have to have one card for one computer. If you do like some people do, and place your router in your ceiling, you would need two cards, one for each computer.

Also, if one of your computers happens to be a laptop, or have a pcmcia slot, you can get this setup to get both in one box.

And in the event I'm talking to fast for you, or you don't know as much about networks as I assume you do, here's some networking basics from Linksys.
