Run Time Error in My Program

Question

I am javing difficulty with a program I am working on and would be grateful if somebody could point me in the right direction as to how to correct my program. I will put the four source files on this post to allow you to have a look at the code I am trying to sort out. It compiles for me but when I try to run it I get the following error:
java.lang.ArrayIndexOutOfBoundsException: 4      
at LayoutGUI.<init>(LayoutGUI.java:63)      
at RunGUI.main(RunGUI.java:9)
