I wonder if a similar toolkit could be assembled for the GUI apps using Zig, Nim or some other fancy new C-like languages plus a minimalistic UI wrapper.
https://github.com/floooh/cimgui-sokol-starterkit
It needs the system's "default compiler toolchain" and cmake, but other then that, there are no external dependencies, and I tried to keep everything as simple as possible (even the CMakeLists.txt file).
All the dependencies (Dear ImGui, cimgui and the Sokol headers for cross-platform wrapping of the platform-specific window systems and 3D-APIs) are bundled right in the git repo.
Zig and Nim are sort-of "in progress" (for instance, see the sokol-zig bindings here: https://github.com/floooh/sokol-zig/)
Get Lazarus IDE for Windows. The language is highly advanced Object Pascal
For the same thing but C++ you can get Ultimate++ IDE.
Either will produce single exe file.
Deployment in either case is just copy exe and have at it
