Well,
PangoLayout *gtk_widget_create_pango_layout (GtkWidget *widget,
const gchar *text);
Would simplify the above. And considering that asking about the
size of a string before you have a widget to draw it on is meaningless,
you wouldn't have the creation of the dummy label either.
(Finding the size of a string is documented in
http://developer.gnome.org/doc/API/2.0/gtk/gtk-question-index.html
BTW)
