Gente, java Fx é muito lokoooo
mas estou com algumas dúvidas:
Antes de eu postar o código, vou colocar minhas dúvidas, ok ?

1º Como Faço o Layout? Tem algum procedimento especial? Só quero colocar os botoes em lugares diferentes;

2º Quando coloco na URL o endereço de uma musica no meu HD, ele da erro , como eu faço pra ele tocar Mp3 , wma ? Só preciso de uma orientação de como fazer;

Segue o Código e o Erro da pergunta 2:

Ahh entendi;
file:/C:/Nasi%20-%20Vivo%20na%20cena%20-%20www.musicasparabaixar.org/03.%20Tarde%20Vazia%20-%20www.musicasparabaixar.org.mp3

Vou explicar o que voces devem fazer, caso alguem tiver duvida :

[code]
File selectedFile = jFileChooser1.getSelectedFile();
URI tURI = selectedFile.toURI();
URL tURL = null;
try {
tURL = tURI.toURL();
} catch (MalformedURLException ex) {
Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex);
}
String toString = tURL.toString();

    System.out.println(" " + toString );[/code]
