I'd submit this is even simpler:

UINT CMyThread::Query()

return (UINT) target->SendMessage(UWM_QUERY_WHATEVER);

ON_[REGISTERED_]MESSAGE(UWM_QUERY_WHATEVER, OnQueryWhatever)

LRESULT CMyWindow::OnQueryWhatever(WPARAM, LPARAM)
{
return dlg.DoModal();
}

Yes, this is how I would do it also. IMHO, prejudice against SendMessage() often leads to unnecessarily complex solutions.
