[untested]

  GtkTextIter end_iterator;

  gtk_text_buffer_get_end_iter (text_buffer, &end_iterator);
  gtk_text_buffer_insert (text_buffer, &end_iterator, some_text, -1);

  gtk_text_view_scroll_to_iter (text_view, &end_iterator,
                                0.0, FALSE, 0.0, 0.0);

However, the scroll_to_iter() part does not work always.  Better to
use gtk_text_view_scroll_to_mark().  If you want the cursor at the
end anyway, you can implement it like this:

  GtkTextIter end_iterator;

  gtk_text_buffer_get_end_iter (text_buffer, &end_iterator);
  gtk_text_buffer_place_cursor (text_buffer, &end_iterator);
  gtk_text_buffer_insert_at_cursor (text_buffer, some_text, -1);

  gtk_text_view_scroll_to_mark (text_view,
                                gtk_text_buffer_get_insert (text_buffer),
                                0.0, FALSE, 0.0, 0.0);

I also suggest that you try to write more readable code.  Using spaces
might be a good start at this.

As another side note, I'd like to praise the GTK+ text widgets.  They
are not easy to start using, but they are very flexible.  Just today
I did some neat things with them and I must say that everything works
just fine.
