Criteria based sharing rule: this is possible, but then you need one rule per possible user. So depending on the org size, this is probably not manageable.

Apex sharing: create a process on the object, and whenever UserLookup__c gets filled in, create a UserLookup__share record for that specific user with the level of access you want to give (read/edit). A great example can be found here.
