Need advice in regards to simple functionality-structure for a website I may build

Question

I would like to create a free literature website but I'm encountering a problem. I don't know how to work the "categories" section.
If I code a category section that is "comedy" or "non-fiction", how do I get all the users who have uploaded stories in these categories to be shown in that category?
Do I first need to add a CMS?
These stories are going to be user submitted but I'm also not sure how they can go about submitting them. I'm not sure if this needs to be done through a CMS or if I need to code something to make this possible.

For this to work, you will need to know some backend web-development which implies knowledge of PHP and SQL database. PHP enables the client to POST information from the client's computer to the database. It is also enables the client to GET requested information from the database.
