You don't have to do the "(const QString &) i18n("&Speak")" cast , and the 
"(QWidget*)speakLayout" cast is wrong. QVBoxLayout is a layout, not a widget
The QLayout is not derived from QWidget.

You must do something like this:

QWidget *widget = new QWidget(splitter);
QVBoxLayout *speakLayout = new QVBoxLayout(widget, 6);
QWdget *label = new QLabel( i18n("&Speak"), widget );
speakLayout->addWidget( label );
