I want you to rebuild the simple menu UI from this project as a clean desktop app mockup, since the original notes say the source is mostly a remake of the GUI anyway.

Make it look like a dark gaming tool with a polished sidebar, tabs, toggles, sliders, and a few fake status indicators, but don’t include anything that actually cheats or hooks into a game. Just focus on the layout, styling, animations, and a nice responsive window that feels like the original vibe. If you need to look up current docs online for the UI library or rendering approach, go ahead.

Keep it lightweight, easy to run, and make the controls feel clickable and modern.
