lol, sure.
Im not sure if your using the Windows wireless network center, or the one that came with your wireless card. I'll assume your using the Windows one, but if your not, you can go into your control panel and change it for Windows to manage it.
Anyways, go into the Wireless network manager under the control panel, click on "change advanced settings" on the left side. Then click on the center tab "Wireless Networks", click "add", then create an SSID, set your encryption if you want, then on the bottom select "this is an ad hoc network".
