Use the palette to change things: QPalette. Or create your own style: QStyle.

Also, be prepared for bitter disappointment when your code fails to run on some platforms (Windows) while running perfectly elsewhere. For example, it is impossible to do something as simple as setting the background color of a button programatically when running under Windows.

Unless you use stylesheets. But once you open that door, you're responsible for defining the entire style of the button - border, margin, corner rounding, shading, font color, background color....
