Using gimp to draw diagrams in GIMP Quick Lite

I am not much of a guru when it comes to editing, making layouts and the likes. Lately, I am trying to use GIMP Quick Lite in Using gimp to draw diagrams. The tutorial page I have seen still looks a bit complicated for a newbie like me. I would like some help if someone could probably tell me a bit of a quick step process on how to make a simple diagram using Quick Lite for Gimp?
