Sorry to say but from what you have written it's bad news. It sound like you have seized your engine.
You might be very lucky worth a try fill radiator with water.
Drain off any oil in engine and refill to correct level with fresh oil and see if engine will turn over on starter motor.
If it starts then you need to establish why it overheated
may be
Leak in cooling system
failed hose
failed radiator leaking
Head gasket
