SSE-Tamil/SIMATS-Browser-Mod-EXE — reverse-engineered prompt

Build me a simple Windows desktop app called SIMATS Browser Mod EXE. I want it to behave like a lightweight custom browser, not a full Chrome clone. When I open it, it should show a clean window with a place to enter a website address, buttons for back, forward, refresh, home, and a simple settings screen where I can change the home page. Please make it easy to build into a single EXE that a normal person can run without setting up anything complicated.

Keep the design plain and professional, with the SIMATS name visible in the title area. If something breaks or a page fails to load, show a friendly error instead of crashing. Add a short README explaining how to run it, how to build the EXE, and what files are important. There are no detailed specs yet, so make sensible choices and look up current docs online if you need to.
