#ifndef DIALOG_H
#define DIALOG_H

#include <QtGui/QDialog>
#include <QPushButton>
#include <QLabel>

public:
    QLoginDialog(QWidget *parent = 0);
    QString GetUser();
    QString GetPwd();
    ~QLoginDialog();
};

#endif // DIALOG_H

3. QLoginDialog.cpp

#include <QDebug>
#include "QLoginDialog.h"
