Changing label values from another class

I used a jpanel form that came with netbeans. I have setup everything up how I want but now I would like to add some events...

For instance... When I click on a button I want event to go to a different class. That is easy enough to do..ie:Dog fred = new Dog()

My problem is that within the class "Dog" I want a method that will change the value of the label in my Jpanel class.

How would I do this?
