Declare attributes instead of using "findChild"

[cjlcarvalho]

You can manipulate your widgets as attributes in SimulatorGUI.

And avoid the constant use of the "auto" type, because it will be better if you specify the variable type explicitly. A good usage of "auto" happens when you are using multiple templates as in T< X< Y, Z > >.
