The hard way (using stats_tree):

static int st_node_msg = -1;
static int st_node_dir = -1;

static void msg_stats_tree_init(stats_tree* st) {
	st_node_msg = stats_tree_create_node(st, "Messages by Type", 0, TRUE);	
	st_node_dir = stats_tree_create_node(st, "Messages by Direction", 0, TRUE);	
}

static int msg_stats_tree_packet(stats_tree *st  , packet_info *pinfo,
epan_dissect_t *edt _U_, const void *p ) {
	const gchar* msg = match_strval(((isup_tap_rec_t*)p)->message_type,
isup_message_type_value_acro);
	gchar src[32];
	gchar dst[32];
	gchar dir[64];
	int msg_node;
	int dir_node;
	
	address_to_str_buf(&(pinfo->net_src), src);
	address_to_str_buf(&(pinfo->net_dst), dst);
	g_snprintf(dir,sizeof(dir),"%s->%s",src,dst);
	
	msg_node = tick_stat_node(st, msg, st_node_msg, TRUE);
	tick_stat_node(st, dir, msg_node, FALSE);
	
	dir_node = tick_stat_node(st, dir, st_node_dir, TRUE);
	tick_stat_node(st, msg, dir_node, FALSE);
	
	return 1;
}

Ain't that hard after all.
