Yes. As a general rule all official Gtk+ widgets return GtkWidget pointers,
so it pays to have all your intial declarations like that. Otherwise, you
must type cast.

No. GtkCTree, (like CtkCList and GtkText) is a widget with it's own
scrolling capabilities, so you only need to use gtk_container_add() to add
the widget to a GtkScrolledWindow. The _with_viewport() part is only for
non-scrollable widgets.

You may also want to suggest the questions you've made to the authors of the
FAQ or gtk+ tutorial.
