How to make a graphical user interface for C++ programs?

Question

C++ / C#

How are C++ program interfaces created? Most popular programs are written in C++, according to Wikipedia. And all these programs have an original and beautiful interface, how to do it? For example, take the same Unity, written in C ++ and has a personal interface, no matter how stupid it may sound. I looked in the direction of Qt, but something somehow did not grow together.
PS Google did not give answers, but maybe I was looking badly.
P.S. Thanks in advance! :)

Answer 1

I looked in the direction of Qt, but something somehow did not grow together.

And it needs to grow. No, of course they correctly write to you that there are still many libraries of all sorts, and they correctly write that many modern libraries draw using OpenGL, but personally I advise you Qt, since you have already begun to get acquainted. I doubt that it will be much easier for you with other libs (especially with WinAPI or c WTL - Cute will seem like a child's toy).
Popular programs have a good interface because their manufacturers have the time and money to make it, and most importantly, the NEED. After all, their products are popular! Adobe is ready to lick Photoshop to a shine, and is able to write its own library, because. it is an expensive product used all over the world.

Answer 2

There is also GTK and WxWisgets. But anyway, then it pulls WinAPI ...

for example the interface of Avast and Norton360 antiviruses are written on it
