DO NOT DRIVE THE CAR. Don't even run the motor with that light on.
Either there is a short in the oil pressure sender (just above the oil filter under the intake manifold) to ground allowing the light to come on, or the sender itself is faulty, or there is really no oil pressure in your motor and you are killing it.
Zero oil pressure is always a "fun" thing to diagnose. The oil pickup tube may be gummed up with sludge due to extreme neglect in oil changes. A valve in the oil filter housing may be faulty (just guessing on this one). Or, like what happened to the previous poor sap that owned my car, something has happened to the oil pump. In my car's case, the owner snapped the timing chain (I'm not sure exactly how...) and the valves crashed and little bits of ex-timing chain, tensioners, sprockets, and hardware went everywhere in the vicinity of the chain. He took it to a not-so-competent mechanic that picked up as many of the pieces as he could, threw in a new chain and tensioners and sprockets and exhaust valves, and sent him back out on the road. The problem was with one particular shard of metal that (ooooh, gravity!) went down. Down in this case is into the oil sump. Three days later the car was towed back in after this piece of metal found its way into the oil pump, jamming it, resulting in a total lack of oil pressure. Thank God he didn't try to drive it. At least I know the head gasket's been done because of this, along with new chain, tensioners, and sprockets, and a set of shiny valves.
Anyway, I really hope your car is not that bad. A few checks can tell you whether to get some wire, connectors, and a soldering iron, or to call a tow truck.
