Pretty hard to diagnose from that.
Is it smoke or steam? Is there coolant in it? is the temperature guage in the red?
If you've lost coolant via a broken pipe or waterpump it could be that.
Is there oil in it?
In either case you could have a blown head gasket and possibly a warped cylder head.
These are just guesses though - I think you'll have to have someone look at it to make a proper diagnosis.
It's not a good idea to drive a car that's got engine warning lights on unless you know exactly what the problem is - these things don't tend to fix themselves.
