So, nothing on this page was any help?
You need to specify a set of options in the MQGetOptions structure that indicate that you wish to receive a particular message from a group. In addition, you should probably indicate that you want to get a complete group.

You may want to try like this...
Open the queue to browse the messages.
Scan all the messages from top to bottom. Check for MsgFlags property value on each of the message. If it is 24 (i.e., Member of a group and Last Message of a Group), this means that this message is the last message of a group.
Count how many such messages there are on the queue.
This number indicates you the number of groups currently on that queue.
You may want to try WMQTool, a wonderful tool to admininster MQSeries. It is FREE and can be downloaded on www.niratul.com.
