If you use Qt Creator:

Add New- > Qt Design Form Class, Derive from QFrame for example. Name is for example MyFrame
Insert content
Open the main window in the designer
Add a QFrame
Right click in the main form: "Promoted Widgets". Add your MyFrame here. Derive from QFrame
Right click on the QFrame inside the main window: Promote to->MyFrame
