Yes, but you need a program that's not supported by Sony or Microsoft so download it at your own risk.
Sixaxis features do not work on PC though.
See attached link for more information.
Just want to add, YOU CAN use Sixaxis features when you use you're own Bluetooth and use a program called, "ScpServer". You will need to install that and install the xbox accessories program since ScpServer hacks the xbox program and makes it think that your PS3 controller is a Xbox 360 controller. To set up ,your PS3 controller you have to plug it into your computer or use a bluetooth so then it's wireless and open the bin folder of the scpserver folder. Once there open "ScpDriver.ex" and keep "configure service" and "Bluetooth driver" checked. click instal and see what happens. If the PS3 is still blinking all 4 lights instead of one then YOU MUST DO THIS.
Open, "My documents", Right click on "my computer or just Computer (sometimes it's labeled differently)" and lift click on manage. Once there click on "Services and Applications". Then click on "Services". Now scroll down until you find "SCP DS3 Services". Right click on it and click start.
Now your PS3 controller will act like an xbox 360 controller (on your PC) meaning Triangle=Y and Square=X. Have Fun!
I don't believe you can use the PS3 Guitar Hero controller on the PC to play anything
It's not about the Game a PS3 controller is designed for the PS3 as a Bluetooth wireless controller that was not designed for the PC or supported by windows software or hardware.
You will need to search for a PS3 to PC driver. After, connect your PS3 to your PC with USB.
Yes you can, but you have to install a Driver in which I do not know where to.
Can't.
No, Modern Warfare 2 on PC doesn't support the PS3 Controller.
No, there are no PS3 -> PC emulators right now, however you can connect a PS3 controller to your PC.

no
Well, according to http://news.filefront.com/how-to-use-a-ps3-controller-on-a-pc/ , you must install a driver in order for your PS3 controller to work on your computer. From there, you can simply plug in your controller and then run ZSNES. ZSNES should regard your PS3 controller as a joystick, or whatever the driver assigns the PS3 controller. However, according to some comments on the above page, you may have some difficulties getting the controller to work with your PC...
To connect a PS3 controller to a PC you need to download a program such as MotioninJoy.
