That doesn't seem too bad, I agree. Maybe that's why QT is used. I haven't really used QT, but the more modern Windows apis, vulkan, etc all are pretty complicated.

FWIW, vulkan is not a GUI library; if you're reaching for it without a clear understanding of why you're doing so, yeah, it'll seem like a very complicated way of doing things.

Thats why I've always like pytk

    from tkinter import \*

    root = Tk()
    a = Label(root, text ="Hello World")
    a.pack()

    root.mainloop()
