Build me a Website

I want a Website somewhat like Wikipedia (but not exactly). Where the website would ask for some data input from the user to show relevant information from the database to the user site.

Also, need an Admin Panel for data input for the website to show.

No fancy Design Website. Simplistic and Minimalistic design for both (User Website & Admin Panel)

HTML, CSS, JAVASCRIPT and use FireBase as a Database(any other reliable database is most welcome). No SQL and PHP.
