UMG hurts my head

I am totally lost with UMG, I see you can make a widget but how do you put up the widget in the game, maybe if I understood that I can start understanding the rest… plz help me…

You need to add it to the viewport. There is a blueprint command for that. Check this out:

There are some more tutorials available scattered through these forums, if you still have trouble, I’ll try to find it.

You should check out the documentation we have available. The Quick Start should be especially helpful for getting a basic UI up and running.
