Try using a C-clamp and just tighten it down slowly. That's what I always use. You may have to open your bleeder screw to take the pressure off but then you may need to bleed the brake afterwards. It shouldn't be sticking like that in the 1st place so you really ought to pull the caliper off and find out why it's binding. If you're lucky it's just dirty and will work ok with some cleaning.

Sounds as if the piston has come completely out of the caliper and needs to be repositioned so that it will slide back in place. If so, lets just hope you haven't damaged the rear surface so that it will never slide back in. The tolerances are very close, otherwise brake fluid would be forced past the seals.
Crawdad is correct, a c-clamp works a heck of a lot better than a hammer. Also, try to apply equal pressure with the c-clamp by laying something (small wrench) across the top surface of the piston. Again because of the tolerances, you may create a leak by applying pressure only to the edge of the piston with the c-clamp so that it is being pushed more at an angle than straight back in.
