There were a few threads, this one [1] is quite extensive
but a little repetetive.

Well, how are they packed ? you can generate them more than once
from the glade file... i'd say the code you're looking for
should look something like the following:

void
fill_box (GtkWidget *box)
{
   for (something about entries) {
      GladeXML *xml;

      if ((xml = glade_xml_new (gladefile, "label-spin-box")) != NULL) {
          GtkWidget *hbox = glade_xml_get_widget (xml, 
                                                  "label-spin-box");

          /* dynamicly append a label/spin pair to the box. */
          gtk_box_pack_end (box, hbox, FALSE, FALSE);

          /* free unneeded resources */
          g_object_unref (xml);
      }

   }
}

That should give you a general idea of how to do what 
you need to do using libglade, ofcourse your implementation
will vary because you probably pack things in a specific way.

Cheers,
