Hello! 

Just wanted to share here the code to build this simple GUI with controlP5. 

We know how annoying is to write code for graphical interface, for this reason I want to share with you the code I usually use and re-use to control the things I do with Processing. 

It is on github here ->  https://github.com/davideoliveri/controlFrame_template 

(I'm sorry I didn't pay too much attention to the graphic output at the moment, just some forms or lines with random parameters, I'm planning to do something more interesting in the next future, by now I was concentrated on the GUI)
