What color is the smoke? Was it white?
The smoke and the loss of antifreeze, and now the inability to drive it, sound like it might be a blown head gasket. If the head gasket has blown, coolant (antifreeze) is leaking into the valve heads and cylinder chambers. Check your oil. Does it look like thick chocolate milk? If it does, it is a sure sign of a blown head gasket.
The repairability of this depends on if the engine overheated and warped the head or the block (head more likely). It will be a expensive repair, and it may be cheaper to get a rebuilt or remanufactured engine instead.
