What are best languages for my web app project?

It all depends on the scope of the project and what information you'll need to communicate to both the server and the user.
I recommend starting with either Python or Ruby. They are fairly simple languages to adapt to. Either language helps communicate between front-end and back-end. Wordpress, as far as I know, uses PHP as its main structure. I, myself, am learning about SQL (Structured Query Language) used in relational databases.
Since you will most likely be inserting, updating, and possibly retrieving information within your app, a database language is paramount. So, if I were in your position, I would start with those three languages to get up to speed working with variables, functions, operators, etc.
