The FOX GUI has exactly this capability, you can connect a variable directly to the widget, without requiring any glue code at all. In fact, you can connect the same variable to multiple widgets at the same time (eg a 'spinner' widget and an 'editeline'), without requiring the programmer to write any type of callback mechanism.
This works because all GUI events are bi-directional. For more information, read: http://www.fox-toolkit.org/datatarget.html
