Calling objets

[limpep]

Hey, I am trying to call a object from once class to another. For exampel if i have 2 class a Welcome class and a Main class, on the Welcome class i have a button called "close" and on the Main class I have 2 buttons "open welcome" and "close". On the Main class i want to be able to call the close button so i can disable it or enable it. If any one can help that would be greate thanks.
