1997 Pontiac Grand Prix Big leak, smoke from the hood and

On my way home in my 1997 Grand Prix it suddenly began letting out a loud rattling sound as I sat idle at a light. Once I start accelerating the sounds increased, then stopped, then picked up again when I came to the next light. A few minutes later I pulled up to my house with smoke coming out from under the hood. The temperature of the car had reached the max and I could hear liquid gushing out from underneath the car. I believe the liquid was engine coolant because it was not so thick.

The next day I tried to move it a few feet from my neighbors house and it would only let out a loud noise and the wheel was locked in place.

What is likely wrong with the car and how much is it to fix?
