Associate to the Contact record with same email of the target entity

[Vincent]

I have a new Entity A which has an email field and a Contact field which is empty by default. I want to do the following:
After entity A record is saved, set the Contact field of entity A record to the Contact record with same email as that in entity A record.

however, it seems that it is not easy to do it in workflow. Is there any trick or workaround to do that? thanks.
