ApioMan3/Compras-Grupo55 ? reverse-engineered prompt

Build me a simple Java desktop app for managing purchases for a small team or store.

I want it to let me register, edit, delete, and search purchase records, and store the data in a MySQL database using the SQL file in the project. It should have a clean windowed interface, since this looks like a NetBeans style project, and the main screen should make it easy to see the list of purchases and add new ones without much clicking.

Please make the app run smoothly from the project as it is, keep the code organized, and wire up the database connection so it actually works. If anything is unclear from the files, use your best judgment and look up current docs online if you need to.
