Naruto has only shown feelings for Sakura. However, I would not mind Naruto ending up with Hinata and then take care of ensuring no more people from the Hyuga clan are given the Cursed Seal Jutsu as promised during the Chunnin exam. This is just in the long run.
But, I don't think Naruto will end up with Hinata unless she can make some kind of impression, which she has failed miserably. Yes, Naruto has noticed her even if it is barely, but really, he has not shown any interest at all. He is completly clueless about her feelings towards him. May be all it takes is for someone to just tell him since everything has to be explained to him in baby steps for the most part. I am not saying it won't happen. I just don't think there are any grounds that prove that yet.
Besides, he is just a teenager. This is the time to have fun with girls and a good time; the formal/serious part can wait a couple of years. ^_^
Nevertheless, Naruto has indicated numerous times his feelings towards Sakura. Sometimes I believe Sakura does feel the same way about him. But, this can also be misinterpreted. This manga can make drastic turns at times. For all I know, she may think of him as a brother.
