Re: component positioning spacing problem
To get better help sooner, post a SSCCE (Short, Self Contained, Compilable and Executable) example that demonstrates the problem. Your problem is achieving a GridBagLayout with spaces between buttons, so post code that makes a GUI with only 2 to 4 buttons in a GBL.

Re: component positioning spacing problem
GridBagLayout does not reserve space for rows and columns that contain no components.
