Well, you've transferred some energy to the wall, and that energy was primarily expended in moving molecules closer to each other, so it's essentially currently stored as electrostatic potential. You haven't moved the wall (not in any 'macro' sense, anyway), so the "Work Done" is zero, but the...

Does "work done" actually have any real meaningful sense or value? I've got no problem with "work done" when moving an object in a conservative field. This makes sense - you've got to put in energy when, for example, lifting an object in a gravitational field, and this energy is the work...
