Need an app that has linked questions and answers similar to a flow chart

I would like to create a resource that can be accessed on a smartphone (either via an app or a mobile-friendly website). The idea is for it be an educational resource, similar to an FAQ, except that all ansers are linked, so after one question is answered, there are then several (up to 5) other applicable questions, based on the answer to the previous question, that can be brought into the foreground in order to be asked and answered. So after the user reads an answer to one question, they can then choose which of the questions they want answered next.

The app will be used by the tutor, so the "questions" are actually what the child is likely to ask, and the "answers" are what the tutor will reply with.

Please see sketch in attached file. So the question being answered is at the top, the answer to that question is below, and then at the bottom are options for which question to have answered next, where the user slides the buttons left or right in order to bring to the centre the question want answered next. Then they tap the centre button to have that question answered. The text in the button then becomes the "Question" on the next screen. This gets answered, and then there are further question below, and so on...

So, my question to Experts Exchange is, what's the easiest way to achieve what I need? Is there an app development platform where I can create something like this relatively easily without coding knowledge? Or perhaps another type of use case (e.g. slideshow, flowchart) that I can modify for this purpose?

Thanks.
