Translate approval outcome

Hi,

I've created an approval workflow in SharePoint Designer. I also installed the Dutch language pack for SharePoint. I've already customized the approval form to Dutch, but how can I translate the approval outcome like Approved, Canceled etc? Or even this page: http://3.bp.blogspot.com/-5x1_6xryYf0/T2_z5oXjF2I/AAAAAAAAFHQ/1KqRcG9dkz8/s1600/SharePoint+2010+State+Machine+Workflows+with+Custom+Task+Forms+(InfoPath)+using+Visual+Studio+2010_Part3+_+24.png

Thanks.
