Best, stylable and cross-platform by CSS GUI library for C++?

Question

I'm looking for library that can do that. I heard Qt is great but I need one which I can style using CSS. Just how java has JavaFX.
It should also have a window maker tool(like Scene Builder for java).
Also it should be able to interact with the OpenGL library. Or else I'll go with GLFW.

Answer 1

From what I heard QT isn't that easy to start with, but it actually uses CSS and QML (similar to HTML) to build UIs. It's also probably the best cross-platform framework for C++ out there. It has a window maker tool inside the QT-creator IDE, too and should be able to handle OpenGL perfectly.
