trigger X on Y__c(before insert, before update) {
  for(Y__c record:Trigger.new) {
    if((Trigger.isInsert&&record.Z__c!=null)||(Trigger.isUpdate&&Trigger.oldMap.get(record.id).Z__c!=record.Z__c)) {
      record.Z__c.addError('Value is read-only');
    }
  }
}

You can do the same with a validation rule, but I presume you have a reason for asking this, so this is one possible solution. Your exact requirements may vary, but this is the basic form of such a trigger.
