7sim/CS2-Internal ? reverse-engineered prompt

Build me a simple C++ project that acts as an internal base for a Counter Strike 2 style test tool, with a clean menu like the screenshot and a solid structure I can extend later.

I want it to open a basic in game style menu, keep the code organized, and include the hooks and core setup needed for an internal Windows project. Make it feel like a real working base, not just a blank template. If you need to look up current docs online for any low level details, go ahead.
