This two GUI libs written in C I just found are really good looking and looks production ready.

Embedded systems:
LittlevGL is a free and open-source graphics library providing everything you need to create embedded GUI with easy-to-use graphical elements, beautiful visual effects and low memory footprint.

Powerful building blocks: buttons, charts, lists, sliders, images etc
Advanced graphics with animations, anti-aliasing, opacity, smooth scrolling
Various input devices: touch pad, mouse, keyboard, encoder etc
Multi language support with UTF-8 decoding
Fully customizable graphical elements

https://littlevgl.com/





General Usage:
Nuklear is a minimal state immediate mode graphical user interface toolkit written in ANSI C and licensed under public domain. It was designed as a simple embeddable user interface for application and does not have any dependencies, a default render backend or OS window and input handling but instead provides a very modular library approach by using simple input state for input and draw commands describing primitive shapes as output. So instead of providing a layered library that tries to abstract over a number of platform and render backends it only focuses on the actual UI.

Features
Immediate mode graphical user interface toolkit
Single header library
Written in C89 (ANSI C)
Small codebase (~18kLOC)
Focus on portability, efficiency and simplicity
No dependencies (not even the standard library if not wanted)
Fully skinnable and customizable
Low memory footprint with total memory control if needed or wanted
UTF-8 support
No global or hidden state
Customizable library modules (you can compile and use only what you need)
Optional font baker and vertex buffer output

They are both good looking and modern in their respective domains. Both written in C so they may each need a D binding for convenient use.

If you are going to mention that then you might as well mention the (imo better) alternative ImGui.

Compare imgui with Nuklear (https://github.com/vurtun/nuklear) and see the difference in the features and polish.

I didn't know this one and it looks nice, maybe not too adapted to big desktop apps.
Based on the screenshots this looks more designed for skeuomorphic UIs or small UIs, e.g mobile dev.

Y'know, even though I'm normally very "native UI or bust!" (outside of videogames anyway), I have to say, for non-native, LittlevGL and Nuklear are *REALLY* nice looking. It's also very, very cool that they seem to be designed with embedded in mind.

Also very cool that imgui appears to have been used for that cool Wonder Boy 3 remake.

I'll definitely have to remember these if I need to do an embedded or in-game-engine UI.

Yes ImGui is more polished and is incredibly easy to extend, creating UI you'll only use once takes no time at all and helps incredibly with debugging those annoying bugs. Blizzard's also contributed to the project so the author is able to dedicate even more time to the project.

Its actually for embedded systems.
