simple, look at the 78xx 79xx voltage regulators

the 7812 and 7805 for the positive supplies and the 7912 and 7905 for negative supply
then you need a transformer big enough. each regulator is good for 1 amp with lots of heat sinking
can't get much simpler

There a lot of articles on converting computer ATX power supplies to bench supplies for +/-12V and +/-5V.
Google: ATX bench supply
