Yes something in that manner.
I am not familiar with GTK, i have done a few things in QT.
I am mainly interested in the information passing.
When i make some change to the input || hit enter || hit the 
button, the scene will change accordingly.

For a more satisfying example, you could have a ball on one line. 
Below that you have a horizontal slider. Whenever you move the 
slider, the ball on the line will move accordingly.
