Help with manipulatable items

Heres a question for you computer super-Geniouses out there......

I would like to make up some objects that are able to be manipulated by a left or right click of a mouse.

Heres my ideas.

Doors........Right or left click a door image and it triggers a identicle Gif of that door opening and a sounds effect of a door opening.

Drawbridge.......Right or left click a draw bridge image and it triggers a identicle Gif of that ddraw bridge opening and a sounds effect of a drwabridge opening.

Traps.......Right or left click a trap image and it triggers a identicle Gif of that trap opening and a sounds effect of a trap springing. (offering a variety of traps.)
----Trap Door
----Saw Blade Traps
----Pendulum Trap
----Fire Jet Trap
----Spring tile Trap
----and so on......

These are just a couple of ideas.

Is it possible to code this stuff with-in D20Pro?

If so I think it could be offered as downloable content that could be sold in themed packs.

Let me know.
