That is the start of the problems with this GUI.
Do not use null layouts, unless defining a layout 
itself (I.E. calling setLayout(null) from within a 
LayoutManager/2 implementation).

Within that layout, the logic will need to account for
the different preferred sizes of components as they 
might appear under run-time environments that might
vary in Java version, screen size and resolution, default
font size/family, PLAF, OS..

I highly recommend the layout tutorial.

I do not find that claim very convincing, given
you ended up here.

A slight change and the 'layout' falls apart?  That is 
to be expected with 'null' layouts, since they are not
actual layouts as such - more 'luck and chance'.

Do the layout tutorial - it should become more clear.
