Qt Creator - How to write an interface?

Question

I just started working with Qt Creator, and I want to write an interface.

My question is: what is the best way to write? Dragging and dropping widgets from a window or writing code?

I dragged some widgets, and I saw that not all the assembly QWidget, such as QIcon, and QMultiLineEditare in the widget view. How to add them?

Thank!
