I have generally used Dauntless. Their private pilot has the question deck for glider I believe. http://www.dauntless-soft.com/products/groundschool/commercial.aspNot really answering your question, Hopefully someone can recommend a good one. It has been a while but I have found the resources for the commercial glider written to be a bit limited and/or of low quality compared to the ASEL commercial written resources. Makes sense as I am sure there are a lot less Glider commercial written tests administered.
