Just-Moh-it/HotinGo — reverse-engineered prompt

Build me a polished desktop hotel management app in Python using Tkinter with a MySQL database. I want it to feel modern and attractive, not like a basic school project, with a clean login screen, database backed authentication, and a simple dashboard.

From the app, staff should be able to add, view, update, and delete rooms, guests, and reservations. Please include logout confirmation, an about page, and some basic charts or visual summaries on the dashboard if that fits naturally. Keep the flow easy to use and the screens visually consistent.

Please wire everything up so database credentials and other secrets come from environment variables, include the SQL needed to set up the database, and make the project easy to run locally. Add sensible form validation, friendly error messages, and enough sample structure that someone can actually test the full app. If there is already design inspiration for the UI, follow that style closely. You can look up current docs online if you need to.
