4n4ndd/Smart-Financial-Calculator ? reverse-engineered prompt

Build me a simple desktop financial calculator app in Java with a clean Swing interface.

I want one main dashboard that lets the user open EMI, SIP, GST, currency conversion, and a scientific calculator from the same place. Each calculator should be easy to use, with clear input fields, buttons, and results that update right away. Please also add a history feature so the app remembers past calculations and lets the user review them later.

Keep the design simple and friendly, like a basic utility app people can use without instructions. Make sure the calculations are accurate, the screens feel connected, and the app runs as a normal Java desktop program. If you need to look up anything current online while building it, go ahead and do that.
