Question flow

Hi, I'm totally new to Bonita, I just followed the 'Getting started video tutorial' and get the key concepts.
But I was wondering if I could use it for the following situation:

We would like to set up some kind of "question flow" (like a 'wizard') in which the user has to fill in a sequence of screens with questions.
The screens and questions that are shown are dependent on the answers given earlier. (so there is some kind of flow with conditions)
At the end of the flow our backend will do some calculations and present the user with a suggested solution and price-range.

However: this flow may not be hard-coded: a non-IT administrator should be able to very quickly alter the flow (add/remove a screen of question, change conditions for the flow, ...)

I was wondering if something like this is possible with Bonitasoft? eg With every screen as a seperate task.

To make things more complicated: the webcontent of the entire environment should also be manageable by non-IT administrators. So some sort of integration with a CMS is also a requirement.

I was checking Bonitasoft for this since we have an application running in production, developed by a third party, that has this kind of functionality and uses Bonitasoft, Drupal, Mysql & BaseX for this.
Unfortunately we have no access to the sources of this application.
So maybe Bonitasoft is used for something different in that application and I'm totally on the wrong track here.
