User Interface / Buttons

Hello,i’ve some problems in understanding how to create a GDI or DX User Interface in a Renderer.
Maybe someone could patch the following for me:
Screen with 2 Buttons, one for start a stopwatch and one for stopping.
And maybe one fader and one Input field.

That would be great! ;)
Tanks a lot!

hello, check the help patches of the button/slider/rotary/… 2d nodes in the addonpack.
