Non-Linear Questionnaires in WordPress

I want to make the following happen in WordPress

1. People answer questions in paginated or single page form.
2. Each next set of options is dependent on the option the user selects preiviously
3. At the end, the user is directed to a page which is a common ending for all questionnaire trees.
4. All this questionnaire options can be viewed/exported

Question: How can this be done? or if there is a plugin available for a similar purpose? If not wordpress, is there another CMS that offers this?

This plugin is capable of doing exactly what you are after
