Olá, faz tempo que não sei o que é “Swing” (sem más interpretações kk).
Mas acredito que falte você chamar o método .setVisible() após instanciar seu JFrame.

JFrame frame = new JFrame("Meu Frame");
frame.setVisible(true);

ps: inclusive, é mais interessante encapsular ele dentro do construtor do seu JFrame, APÓS as configurações do initComponents();

Aqui amigo, seu problema é q vc fez um loop, e ele n termina a condição, sendo assim ele n mostra a interface. Apague este código ou deixe comentado ( // ) a invocação do método valordesensor() na classe construtora e vc verá que o mundo fará mais sentido e estará próximo de responder todas as perguntas sobre o universo.

Resumindo, faça isso:

public GUIcrontroleJ() {
    initComponents();
  //  valordesensor(); // Xablau
}

kkkkk vlw
