You should use a program called DS4Windows. It makes the DS4 work as an XBox 360 controller, but it includes a lot of extra functionality.
First of all, the rumble feature.
For Gamecube games, I mapped the right mouse button to L1, the mouse movement is done with the touchpad, and a macro (SHIFT+R) to the share (select) button. I also disabled mouse acceleration for the touchpad. I did those mappings for this reason: holding the L1 button and using the touchpad moves the free look camera (enabled in the graphics options) and the share button resets the camera.
Greatest controller I've ever had (I bought it last week).
