I have used them for getting text from a textview
GtkTextIter textiterstart;
GtkTextIter textiterend;

textbuffer =
gtk_text_view_get_buffer(GTK_TEXT_VIEW(propdata->comments_area));
        gtk_text_buffer_get_start_iter(textbuffer, &textiterstart);
        gtk_text_buffer_get_end_iter(textbuffer, &textiterend);
        
comments = gtk_text_buffer_get_text(textbuffer, &textiterstart,
&textiterend, TRUE);

Iterators are used to mark a position in a datastructure (in this case a
null terminated string).  They provide an interface for accessing data
and walking data in a liniar fashion (Iterating over a data structure).

I don't understand the question.  Borders are drawn by the windows
manager and there is no way to embed widgets in them.  You can change
the titlebar text but the gnome-HIG cautions against it.
