Not sure of the official way but this may work:

 GdkWindow *window;
 GtkWidget *widget;

 window = gdk_selection_owner_get (GDK_SELECTION_PRIMARY);

 if (window)
    widget = gdk_window_get_user_data (window);
 else
    widget = NULL;

You still have the problem that you have to write code like this:

  if (widget)
    {
      if (GTK_IS_EDITABLE (widget))
        /* cut/copy for GtkEditable *; 
      else if (GTK_IS_SOMETHING_ELSE (widget))
         ;
      ...
    }

GTK should probably have a solution to that, but it doesn't.
