Yes, its possible but there is no OOTB code in DD4T handling Condition Tags. You will get the condition list in your component object.
But after that You have to write your own code to handle it as per your requirements i.e. what component you want to remove or show from your current list of presentation according to your conditions.
Reference from my blog but it is in c# & will give you hint how to implement.
Update: as mentioned by Raimond above, de-serialization part is due in April.
