JavaFX - criando menu personalizado

"Bem-vindo ao maravilhoso mundo de java".
O java através de sua poderosa API javaFX,
permite a seus programadores personalizarem
seu próprios menus, e isto é muito especial.
Quanto mais se conhece destes recursos
e se sabe aplicar mais profissional ficará seu programa.
Neste exemplo estamos adicionando um Button,
um RadioButton, um Label e um CheckBox
para selecionar opções em um menu personalizado.
Mas ainda existem outras subclasses MenuItem
disponíveis para usar como opções de menu
que não estão sendo utilizados neste exemplo.
