int main(int argc, char *argv[])

QApplication a(argc, argv);

QWidget* widget = new QWidget();
widget->setWindowTitle("My App");

QGridLayout* gridlayout = new QGridLayout();

QLabel* label = new QLabel("Name:");
QLineEdit* lineedit = new QLineEdit();

gridlayout->addWidget(label, 0, 0);
gridlayout->addWidget(lineedit, 0, 1);

QLabel* label2 = new QLabel("Name:");
QLineEdit* lineedit2 = new QLineEdit();

gridlayout->addWidget(label2, 1, 0);
gridlayout->addWidget(lineedit2, 1, 1);

QPushButton* pushbutton = new QPushButton("OK");
gridlayout->addWidget(pushbutton, 2, 0, 1, 2);
