Could you build this?
No Creating a cross-platform C++ GUI framework targeting Wayland, X11, Cocoa, and Win32 requires deep systems programming, windowing system internals, and graphics rendering expertise.
What it would actually take: Requires a C++ systems framework implementing BeOS's BApplication/BWindow API, backed by native windowing backends (Wayland protocols, Xlib/XCB, Win32, AppKit) and a 2D software/hardware rasterizer (e.g. Skia or Cairo) with custom event dispatching and multithreaded messaging architecture.
