Each scrollbar uses 4 different styles (background, up-button, down-button, thumb). Those more complex elements just uses other simpler elements internally.
You can build more complex functions on your own. The GUI system is that simple to provide the best extensibility.
You can learn a lot about the GUI system by using ILSpy or any other .NET reflector.
