By "based on UDP", do you mean:
1) your protocol is an unreliable transport-layer protocol similar to
UDP but not the same as UDP
or
2) your protocol runs on top of UDP?

If the answer is 1), then, if your protocol has port numbers, you get them from
your dissector.
If the answer is 2), the packet_info structure pointed to by the "pinfo"
argument to your dissector has "srcport" and "dstport" members that, for a
protocol running atop UDP, have the UDP source and destination port numbers.
