[Resolvido] Erro em conversão de variável

Eai gente, to tentando converte o valor de um TextField (string) para int (ou double, se nao tivesse dando erro):

public class REL extends JPanel {

    Wallpaper jframeWallpaper = new Wallpaper();

    int colunaRetangulo = Integer.parseInt(jframeWallpaper.colunaRetangulo.getText());
    int linhaRetangulo = Integer.parseInt(jframeWallpaper.linhaRetangulo.getText());
    int larguraRetangulo = Integer.parseInt(jframeWallpaper.larguraRetangulo.getText());
    int comprimentoRetangulo = Integer.parseInt(jframeWallpaper.comprimentoRetangulo.getText());

    public Rectangle2D r(){
        return new Rectangle2D.Double(colunaRetangulo,linhaRetangulo,larguraRetangulo,comprimentoRetangulo);
    }

Quando eu coloco os valores no textfield e clico no botao pra desenhar as imagens, invez de aparecer o JFrame que está o desenho, o JFrame principal (onde eu digito as informações) abre novamente, e volta esse erro:
