Preciso muito de ajuda. Como atuar nos controles.

[lc_PapaiLu]

Estou desenvolvendo um simples Jogo da Velha, e como os controles (Botões, Labels etc) ficam em outros JPanels não consigo evelouir no projeto.

Preciso que alguém me ajude a:

A cada click nos botoes do jogo, o JLabel (lbl3) que fica no  pnlTopo receba o valor sinal (letra do jogador. Acredito que os demais problemas eu possa dar sequencia sozinho.

Obrigado por qualquer ajuda. Sei que parece ser simples, mas realmente eu, não estou conseguindo e preciso chegar ao fim do projeto.

Segue o Codigo completo:
