You may be able to power wheelie with a bounce in first gear, but I wouldn't recommend it.
Go about 25 mph or get your rpms around 7,000 and slip the clutch in, give it some juice and slip the clutch out again. It should jump forward. Now try it agian with more throttle after pulling the clutch in.
You want to release the clutch like you are pulling into fast moving traffic from a stand still. Not dumping and not feathering it.
