c-gleison/FinTrack-JavaFX ? reverse-engineered prompt

Build me a simple desktop app called FinTrack for keeping track of personal money in and money out.

I want a clean Java app with a friendly interface where I can add income and expense entries, see a running balance, and view my recent transactions in a list. It should feel easy to use, with basic forms for date, description, category, and amount, plus simple summaries so I can quickly see where my money is going.

Please make it polished enough to run as a small local finance tracker, with sensible defaults, validation for bad input, and a layout that looks modern and organized. If you need to look up current JavaFX docs or best practices while building it, go ahead.
