No metodo private void btnClicActionPerformed, ao inves de lblResul = setText(Double.toString(soma));
coloque lblResul.setText(soma); ou lblResul.setText(Double.toString(soma));

Vlw pela ajuda, eu substitui o comando lblResul = setText(Double.toString(soma)); para lblResul.setText(Double.toString(soma)); e funcionou. Vlw mesmo cara.
