int main(int argc, char **argv)
{
    QApplication a(argc, argv);
    MyMainWindow w;
//    a.setMainWidget(&w);  //qt4中不用这个了，没有主窗口的概念了。

    w.show();
    a.exec();
    return 0;
}

qt4.3.5下编译的，

qmake -v 看一下是不是 4.3.5版本，

如果是的话

$qmake -project

$qmake

$make

就可以了，要是3.1版本的，就要稍加修改一下了

补充添加： 

QT中文化之完美字体
中文化与richtext之结合：
QString str(tr("This is a string!"));
QLabel *label=new QLabel(""+str+"",0);
