The existence of tools such as Qt Creator has made designing applications' user interfaces an easy and fun job for the developers. We no longer need to write a bunch of code just to create a single button, or change a bunch just to adjust the position of a text label, since Qt Designer will generate that code for us when we design our GUI. Qt has applied the WYSIWYG (what you see is what you get) philosophy into the working pipeline and it provides us with all the convenience and efficiency we need to get our jobs done.
In the next chapter, we will learn the ins and outs of Qt Creator and start designing our first GUI with Qt!
