While answering questions from fans, Sony Computer Entertainment Worldwide Studios President Shuhei Yoshida confirmed via Twitter that the new DualShock 4 controllers for the PlayStation 4 will function on a PC.
@Napo2k the analog sticks and buttons will work just fine

Yoshida went on to state that basic functions will be recognized by default on a PC, but, for more specifics, we’ll have to wait until after launch for a full field report.
Although Yoshida doesn’t specifically rule it out, the “share” button is unlikely to be recognized, at least not without a specific driver update and/or players mapping alternative functions to it. The motion sensors and light-bar are unlikely to work either.
PS4 controller will cost $59.99 separately, making it an expensive PC controller, especially considering that it will have some limited functionality. Each PS4 will contain a Bluetooth enabled controller though, so if you are purchasing the system you get a PC controller included.
