Custom player interactable GUIs?

I'm brand new to DMing in Roll20 and I want to have physical puzzle solving in my campaign. Is it possible to have a GUI that players can interact with by turning dials, moving gears, pushing buttons, etc. I could make it as a separate app that I just give to the players to open at the right time but it'd be more immersive if it can be done in Roll20 and awesome if such a thing already exists. Side note: I will be getting a pro account very soon but don't have one at the moment.   

Hi Cherissa! Mod scripts can react to objects having their position or rotation changed, although I am not aware of an off-the-shelf script for this purpose. Actions can also be attached to objects on the VTT that can be triggered via API command buttons on the top palette that appear when they are selected. At this point however, there are no VTT elements that can trigger an action simply by clicking on them. This has been a long-standing request by a few folks, but has never been developed.
