    How can the posted code be compiled and executed for testing? It does not have a main() method.
    If you don't understand my answer, don't ignore it, ask a question.

    For one thing, your code formatting is not so good. If you're going to ask volunteers to set aside time to help you, the least you can do is to put in some effort yourself to post only well-formatted (and preferably compilable) code. I suggest that you don't use tabs for indentation but rather spaces, and 3 spaces ought to be sufficient. Please be sure that your indentations are uniform across a block of code. Please avoid excess whitespace and avoid too little whitespace as well. There are Java code formatting guidelines that can help you with this.

    Next, don't override a JPanel's paint method but rather its paintComponent method, especially if you're doing animation since the latter has double buffering help by default. Next and your main problem: *never* dispose of a Graphics object given to you by the JVM. So that line
    g.dispose();

    simply get rid of it.

    Else the program will have no Graphics object to draw its child components like JButtons and such.
