    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.

    ok I modified my code and made the code with two buttons. Please help me figure out how I can add horizontal and vertical spaces. Here is my new code.
    Java Code:

    GridBagLayout does not reserve space for rows and columns that contain no components.
