build a simple 6 window java app using java swing or javafx and use apache derby database to store info and retrieve info

this is a university level project to build a simple 6 to 7 window java app using java swing or javafx and use apache derby database to build an application. This can be done in 12 hours for a student and 4 hours for an expert. I know this because I am a programmer myself but I dont have time for this. I need this done by Friday night so in two days max. When you start the application it will display a window with a list of users from the database you can click on any of the user or you can click register new user. There will be no account management or log. Just simply register a new user with first and last name that is it and store that information in the user table, simple. when you click on a user you can make a post (like twitter a few character maybe 120) you can also see a list of all the post of that user. Also there will be a button shopping, when you click on shopping you will see a list of "fake" items, just 5 items. you can click buy and it will add that item to a table. there will be a button called items that when you click will you show which item a user has bought. I have screenshots of what the final application should look like and i also have more details in the attached document. this is NOT in in depth application there is no account management or cart or login or password just storing things in the database and reading things from the database and displaying in the window.
