If you search SpawnWave PSP Go on YouTube, his latest video on it was released about a week ago and I remember him commenting on this very point.
I think natively no, you need a PS3. Insane, really.
Enjoy the PSP Go - I had one about five years ago. Fancy picking up a Vita at some point.
It was possible, however I came to learn a couple of things.

Better DS3
After setup, I could get almost through the sync process but it would fail picking up the controller with error '802F0153'
Looking online this was due to a fake dual shock 3 (DS3) controller. I cracked it open and inside the battery just had a blue covered and appeared to be glued to the circuit board, the board solder was also rubbish.
I went to eBay and purchased and 'Official Sony DS3 controller' for almost £20, this one arrived and the same error occurred. I didnt bother cracking it open, instead returned it for a refund but I expect it was similar to the one I had before.
Next I went to see my parents and took a laptop and screwdriver. My dad has an old PS3 and for some reason 3 DS3 control pads. I cracked one open and it was a world of difference. CE stamps and writing all over the battery, good soldering. Low and behold it synced straight away without any issues at all.
The main difference externally was the R2 and L2 triggers. On the real ones they have good feedback and feel 'softer' on the fake they are more clicky with much less feedback.
Spot the difference...
