emmanpbarrameda/Employee-Payroll-Management-System-Java-GUI ? reverse-engineered prompt

Build me a desktop Employee Payroll Management System for a small company using Java Swing and a MySQL database.

I want a clean login screen, then role based access for Admin and Super Admin. Admin should be able to manage employee records, create and edit user accounts, and generate payslips. Super Admin should have full access to everything, including system settings and audit trail records. The app should also handle bad input nicely, like letters in number fields, and show useful error messages.

Please make it feel polished and modern, with a nice splash screen and a UI style that looks better than the default Swing look. I also want payslips to be generated as PDF files, and all important actions should be logged so I can see who did what. If it makes sense, include an easy installer or packaging setup too. Use current docs online if you need to.
