Your GUI problem aside, you've got some code design issues to deal with. Why is your button class (not going to get started on the Java Naming Conventions either) a JFrame? It's not. Your random class is not a JPanel... These are things you need to fix before you start worrying about the actual gameplay.

This is the code and i have no problem i'n its execution.Can you help me for what i am asking

I want to move from one button to an other depending on the roll of the dice

Can you explain what you mean by "move"?
What is a user supposed to do when using your program?
What is the program supposed to do?
