App with Webflow tools ? Can be done?

Hello!!!. 6 months ago I started programming, so I’m taking my first steps. I have an idea to make an app, but I need a little guidance. I am trying to make an app, which through prior registration, allows you to simply invite other users at a certain time to an event or game, which they have to accept or reject the proposal. With Webflow tools, will it allow me to create it? how? Thanks for the time.
