CAknQueryDialog API can also be used as a confirmation query, following function illustrates how you could use it for this purpose:

TInt ShowQueryDialogL(const TDesC& aMessage)
{
	CAknQueryDialog* dlg = CAknQueryDialog::NewL();
	return dlg->ExecuteLD(R_QUERY,aMessage);	
}

another usage...

TBool ShowQueryDialogL(const TDesC& aMessage)
{
	CAknQueryDialog* dlg = CAknQueryDialog::NewL();
TBool answer( dlg->ExecuteLD( R_QUERY,aMessage ) );
	return answer;// True=YES, False=NO	
}

As all dialogs CAknQueryDialog also requires resource definition, with this example function you could use following resource definition:

RESOURCE DIALOG R_QUERY
    {
    flags = EGeneralQueryFlags;
    buttons = R_AVKON_SOFTKEYS_YES_NO;
    items =
        {
        DLG_LINE
            {
            type = EAknCtQuery;
            id = EGeneralQuery;
            control = AVKON_CONFIRMATION_QUERY
                {
                layout = EConfirmationQueryLayout;
                animation = R_QGN_NOTE_INFO_ANIM;   
                };
            }
        };
    }

If you want to use confirmation queries without resource definitions, you could also utilize CAknGlobalConfirmationQuery API for example like this:

TBool ShowQueryDialogL(const TDesC& aMessage)
{
    CAknGlobalConfirmationQuery* QlobalQ = CAknGlobalConfirmationQuery::NewL();
	CleanupStack::PushL(QlobalQ);
 
	TRequestStatus theStat = KRequestPending;
	QlobalQ->ShowConfirmationQueryL(theStat, aMessage, R_AVKON_SOFTKEYS_YES_NO);
	User::WaitForRequest(theStat);
	   
	CleanupStack::PopAndDestroy(QlobalQ);
	if(theStat.Int() == EAknSoftkeyYes)
	{
		return ETrue;
	}
	else
	{
		return EFalse;
	}
}
