Problem aligning components on a panel using GridBagLayout and GBC

I am developing a GUI where I will be having several rows of label/textfield pairs ( each row will have at the most 3 pairs ). I just started with 2 rows. The first row has 2 label/textfield pairs and the second row has 3 label/textfield pairs. I am running of out ideas on how to make them aligned properly. Any help is appreciated.
