Placing labels in a panel

Attached is code I am using to display labels and text fields on a panel The JFrame was created using Netbeans. The data with the order the labels should be displayed comes from a mysql database. I have the info available in property display and now need to get it to display on a panel on my frame. I've tried as few things like setvisible and pack without any success so I am either not getting them in the right place or they are not the answer. Any ideas apprediated
