If you've got a VAIO, yes. Sony have made a simple bluetooth application. I use it with my laptop and PS3. Pretty sure there's a modified version floating out there, for any bluetooth compatible PC.
USB keyboards are only 3 or 4 pounds in the UK, you can get something smaller for a bit more money (IT logic ). It's probably simpler, easier and cheaper than faffing with the laptop.
I didn't want stuff lying all over the place in my family room (head set, controllers, gaming rig, etc) so I got a small keyboard to mount on the controller: http://www.amazon.com/dp/B001ENPDJA/?tag=gtplanet-20
