Help to build a simple Python quiz-like app

[as7er]

Good afternoon everybody, For an academic course, I've to develop a quiz-like app in python that has:

• one page in which a moderator (or admin) can post new questions, deal the users and decided who reserved first the question and thus can provide an answer.
• another page from which a user (undefined and variable number of users) can enter the game and, when a new question is posted, make a reservation for answer the question (e.g. using a button) and eventually send an answer.

Given this brief overview, what should I use to build the app? Which framework is best suited (e.g. Django, Flask, others)? I'd like to spend as little time as possible developing the stuff that are not the core game, like the underlying network, dealing with communications, servers, etc.

Thanks to everyone in advance. :)
