Swing JAVA App with Database

Hello,
I Need a MVC Java app that connect to a Database, mainly a CRUD app with Swing (Jframe,…).
It will be a main Jframe with some tabs, it’ll be used for property rental, it need to be a really clear code and basic functions, basic MVC.
I added a file to show you the main tabs.
I can provide you the database too.
If you have a french expert, would be maybe better.
I really dont know what the price could be for these basic kind of apps.
