First call:

PangoLayout *layout = gtk_widget_create_pango_layout(widget, "text");

on the widget that the string will be used for (different widget styles 
mean that you can't make a general function).  Then call:

pango_layout_get_pixel_size(layout, &width, &height);

To get the width and height.  Make sure ou free 'layout' when you're 
done with it by calling:

g_object_unref(G_OBJECT(layout));
