Gui web interface builder for react

Hi #react,

I am a newbie to react. (I started by adding some components to someone else's hello world app). Is there a https://material-ui.com/ based gui builder or should I build one - cutting as many corners as possible - preferably written in React (to get my React up to speed). I would have to get nodejs to do the file (re)writing.

Thank you for your time,
Turloch
