When you speak of the Qt Creator you certainly mean the controls on the left and right. In my opinion, the best thing to implement that are QDockWidgets. Have a look at them in the docs and as Martin said, look at the examples, they are perfect to learn each of the layout and composing issues.

QDockWidgets can be made floatable (undock them from the main window as toolboxes), they can have fixed sides to be docked on and it's easy to use them, because they can be filled with every widget you like. I often use them when I show a file explorer in an application, for example. Just look at the examples and play with it.

If you just want to have QActions visible all the time for the user, you can use a QToolBar.

You normally start with a QMainWindow and then put other toolbars, controls, widgets etc inside that.
