If i hold a button a hud comes in screen Plays what i want?

So what i want is,

If i hold TAB, A Hud comes in screen and you see 4 Pictures of Animation so whenever i move my mouse on the hud i can click on it and it will do the animation i chose.

Is that possible or is that only possible with C++?

Yes that is possible without the use of C++.

And is there a tutorial how i do this? or somewere that helps me that way?

I would start with creating a widget with 4 buttons. Make the buttons your animation images. For onClick events for your buttons, play the animations you want to play
