Answer 1

Generally, I create and add the components of a GridBagLayout in Y, X position order. I don't know if this is required, but it makes it easier for me to diagnose problems.

Here's what I came up with for your grid.

Component   xPosition   yPosition   xWidth   yHeight
---------   ---------   ---------   ------   -------
S1              0           0          2        2
S2              2           0          2        1
S4              4           0          2        2
S5              6           0          2        1
S7              8           0          2        2
S8              0           2          5        1
S3              2           2          2        1
S9              5           2          5        1
S6              6           2          2        1
