So I have to gtk_widget_ref( "Everything in that box" ), before I
gtk_container_remove( box )  ??

I'm not quite following this.  I have never used ref/unref before.  Does
this manage a counter to see if the widget is still in use? 

I noticed in the gtkcontainer.h file, there is a function called
gtk_container_children which returns a list of items, the children widgets
I'd assume.

Is it safe to just step through that list destroying them all, or would I
have to mess with unref/ref still?
