No, the OP wants a round robin. In the Swiss pairing a new drawing is made after each round. The OP should forget about the additional constraint of having the best player play against the worst in the first round.

There are many ways of doing round robin pairing, and I'd think a quick google job should find some ready implementation. Pick one, and after the schedule is made, just assign the players in such a way that the best player plays the worst, etc. So if whatever algorithm you implement says the first round is "1-2, 3-4, 5-6", then give the best player label 1, the second best label 3, the third label 5, the label 6, 4, and the worst player gets label 2.
