Quick and dirty:

struct Style : QProxyStyle
{
    void drawControl(ControlElement element, const QStyleOption *opt, QPainter *p, const QWidget *w) const
    {
        if (element == QStyle::CE_TabBarTab) {
            QFont f = p->font();
            f.setBold(true);
            p->setFont(f);
        }
        QProxyStyle::drawControl(element, opt, p, w);
    }
};

...
    yourTabWidget()->tabBar()->>setStyle(new Style);


May need some polish.
