Constructive Feed Back (Java Program)

[xddxogm3]

I wrote a Java program and want opinions on what I can do to improve the interface. I understand it is a minor and inconsiquential program, but I feel it would be good for my developement to get other opinions on it. Remember this is my first program ever with Java. I also just have a command text field that shows action executions only no other functionality.
