Kaspar, While you probably can find the kind of tool you are looking for (I don't know of any since I don't have a need for them), I would question your data design. You should be able to design your data so that users can add questions without changing the data structure, just the data content. Then, you can build your app with a set data structure, but the data can be completely dynamic. This would result in the same experience for the user, but a lot less work for you and most likely less fragility for your data.
