noarche/ComboToolPro-GUI ? reverse-engineered prompt

Build me a simple Python desktop app that helps me clean up and organize email and password combo text files for legitimate testing and data cleanup.

I want a GUI with text boxes and buttons instead of using command line files. It should let me load combo text, remove duplicate lines, sort lines A to Z, split email from password into separate outputs, extract just the passwords, pull out URLs, find MD5 hashed passwords, and separate lines by domain into different text files. It should also be able to combine multiple files into one, split a large combo into smaller chunks, and rejoin emails with passwords after passwords have been processed. Add a small summary view that shows top domains, total lines, and basic percentages for the loaded combo.

Make it easy to use, save outputs clearly, and avoid overwriting important files unless I choose to. If you need to check current Python GUI best practices, look up the latest docs online.
