What is possible with a question widget?

I am realizing that what I want to do is beyond the basic capabilities of Captivate and I will have to get someone to create the widget for me. I want to make sure that what I am asking is possible (even as a widget).

I will be using an LMS

I am creating for a semi-literate audience.

I have Captivate 4 and would like to create a widget so that I can use it again and again to create new questions.

I want to create a hybrid multiple choice/hotspot question - the hotspots are over a video containing the question.

Ideally there is no "submit button" the question is answered on the first click. (This is not a dealbreaker)

After a wrong answer, a video is played explaining why the answer was wrong, then the question plays again and the user can try another answer.

This is where I am currently stuck. The previous answer needs to be cleared (as if the clear button was pressed) Can this be accomplished from the widget?

I also want each wrong answer to branch to a different video clip but return to the same question (or better yet a different question from the same pool in which the choices are the same but rearranged (we can create multiple versions of the question video .

Here is as far as I have gone. Correct answers work, the problem happens when the user selects a wrong answer.

Try a right answer first (the hand with the blue bandage) then try a wrong answer (not the guy in the white coat)

Is this something that can be done with a question widget or am I better off having a developer create something from scratch in flash? I need to work with an LMS.
