QGroupBox issues

[Inzinejkr]

Okay, I'm trying to group up some labels and line edits in a stacked widget, but I'm having trouble understanding how to do it.
Currently, I have this code:

    int z=0;
    for (int i=0; i<3; i++)
    {
        QVBoxLayout *vertical=new QVBoxLayout;
        QWidget *page = new QWidget;
        for (int j = 0; j < 5; j++) {
            //QGroupBox *grp=new QGroupBox();
            QLabel *lbl=new QLabel("Something("+QString::number(z)+")");
            QLineEdit *txt=new QLineEdit();
            vertical->addWidget(lbl);
            vertical->addWidget(txt);
            z++;
        }
        page->setLayout(vertical);
        ui->stck->insertWidget(i, page);
    }
        ui->stck->setCurrentIndex(0);

This code looks like:

What I would like to do is:

The purpose of this is I'm making a quiz maker for my school project and this is how I'm thinking of grouping questions with answers, if anyone's got a better idea, let me know.

        for (int j = 0; j < 5; j++) {
            QGroupBox *grp=new QGroupBox();
            QVBoxLayout *grpLayout = new QVBoxLayout();
            QLabel *lbl=new QLabel("Something("+QString::number(z)+")");
            QLineEdit *txt=new QLineEdit();
            grpLayout->addWidget(lbl);
            grpLayout->addWidget(txt);
            grp->setLayout(grpLayout);
            vertical->addWidget(grp);
            z++;
        }
