I did this back in '99, in VFP5. I had at least three tables - one for question types (which class will be instantiated), one for questions themselves, one for questionnaires (i.e. sets of questions, as there were more of these), and one for answers. The other tables (who the answers belong to, etc) were involved on the side.

Each question was represented by a container; the container had on it controls corresponding to that type of question. The yes/no questions had an optiongroup of two buttons; most of the questions required answers from 1 to 9 - that one had an optiongroup with radio buttons arranged in 3x3 square. There was a type of question where a long text was expected - it had an editbox. Some had a yes/no/if not, why - optiongroup with 2 and an editbox. All containers had the same width.

A questionnaire with appear on a form as a bunch of such containers one below another, all of them in one very tall container which then was in another container which was as big as the form would allow. The tall container's .top was adjusted as focus shifted to the next question (so it was mostly negative), which provided the scrolling of questions in the form.
