All Moody had to do was make a portkey while Harry was in his office and have him touch it. Alternatively, he could brought him outside the grounds and apparated with him. Harry had no reason to suspect him and surely would have done what Moody would tell him to do. Furthermore, I highly doubt that if a student would disappear, Dumbledore’s first reaction would be to suspect a teacher of abducting the student, much less Moody whom he specifically brought in to increase security and trusts implicitly. In a magical school there are so many more basic things that can happen to a student, that questioning Moody would be far down the list. And anyway, the way Moody did do it is practically begging for Dumbledore to suspect him. Moody volunteered to carry out the cup, Harry touched the cup, and then the cup comes back without Harry. It would be almost blatantly obvious that Moody had made it a portkey.
