got a conventional panel with relay based oeration. The relays are operated via normal push buttons as an wehn required. Now i want incorporate a touch screen or touch based buttons without changing the panels or its relay logic. can this be accomplished. If Not what are the changes that should be brought in. How much can it cost.

Depends on the touch panel type, may have discrete "buttons" or continuous (x-y) position sensing, newer types are "multi-touch" sensing two or three touches simultaneously.

In any case, a microcontroller or dedicated touch controller should be able to translate the touch input to the intended button actions.
