    QHBoxLayout *buttonLayout = new QHBoxLayout;
    buttonLayout->addWidget(previousPushButton);
    buttonLayout->addWidget(okPushButton);

    QLabel *nameLabel = new QLabel("&Name");
    QLineEdit *nameLineEdit = new QLineEdit;
    nameLabel->setBuddy(nameLabel);
    QHBoxLayout *nameLayout = new QHBoxLayout;
    nameLayout->addWidget(nameLabel);
    nameLayout->addWidget(nameLineEdit);

I don't see you call setCentralWidget(QWidget *) in your MainWindow constructor. You need to look at QMainWindow::centralWidget() explanation.
