Do a search in the Power Supply Design forum. There are at least 6 different threads in (+/-) bi-polar output supplies going right now.

From what you ask, +/- 39V from 220VAC line is nothing out of the ordinary. Depending on how much current you want, you will go with either half-bridge (200-1000W) or a full-bridge (>1kW) topology.
