What knowledge should I have to make my web app?

First of all, thank you for your time in reading this question. I am in charge to develop a website project for my university club, but I don't have web development experience prior to this. The project consists in a simple website that asks you to login with your university email and then asks you 4-5 questions. In the end, there is a table with all different people and what they answered. If you click on one line, it shows the contacts of their person and more additional information.

I was thinking to make it with Flask or Django. I have basic knowledge of Python/R/Matlab. What do you suggest to use as framework, what should I learn and how many hours can it take? I asked multiple people already and everybody has different ideas about flask and django and not many people know about the CMS available for those. In case it exists, I would be down to use a pre-existent template.

Thank you again, I know how much time is valuable for your all.
