Creating a customisable quiz

Hi, at the moment I have a quiz very similar to the quiz template which macromedia/adobe give users. My structure of the application is that I have one scene which deals with a welcome screen and the menus. I then have another scene with all the questions and images on and then a results frame at the end.

What I am trying to archive is a stage/frame which will allow the user to edit the current questions in the quiz, add new ones, and delete old ones. It will also give them the ability to choose what type of E-Learning component they would like to use, be it drop and drag or multiple choice along with giving them the ability to add pictures to the components.

If you have any ideas where i should be looking to do this, and how I would be so grateful.

Thanks, Divardo
