I think so, if pcap_pkthdr is one of the fields in the packet struct:
typedef struct packet{
		int packet_number;
                struct pcap_pkthdr *pkt_header; //points to the header of a 
packet
                const u_char *pkt_data; //packet data
		struct packet *next; //pointer to next node in list
	} packet;

and if I'm creating a new one of these nodes for each packet that should 
cover it right?

I'll admit, getting my head around pointers is definitly not one of my 
strong points. Since I can pass this->SniffEther->pkt_header directly to the 
function to update the gui I just assumed I could assign it to 
tail->pkt_header the same way.
