How would you design a sane, non bloated and simple GUI library?

Something like GLFW where the full extent of the library is to create a window, define its basic parameters, and include the other 2 or 3 features that your specific library is geared towards. For example GLFW basically just has what I said above plus function calls for creating an OpenGL/Vulkan context within the window along with function calls for full screen, input, and a monitor reference for refresh rate and getting necessary information about video and display settings.

I would acknowledge that it's not that easy.

Figures you can make it in most regards sane and offer nice graph etc. structures that let you layout and render any sort of UI elements.

But it won't be simple and non-bloated when that needs to work well on an actual OS.

JavaFX. Every GUI element is simply a data structure of GUI elements.
