Before I answer your answer, I want to say that I also disagree with the second answer. Lessons can be very worthwhile. The part about developing your own style because you do not have a teacher is pure rubbish. A good instructor will encourage you to develop your own style. I have no data to support this, but my gut feeling is that people who learn without lessons are more likely to simply copy the style of what they hear and see, because they have no one to encourage them to go beyond that. However, not everyone does have access to a teacher. Not everyone can afford private lessons. So, while private lessons are worthwhile, not everyone is going to get them.

Now to your question. Yes you can learn. Many of us originally learned without lessons. Back in my day, there was no one giving rock guitar lessons in the area. That was pretty much the case back in the 50s and 60s. Yet, a lot of good guitarists learned to play during the 50s and 60s.

It is much easier to learn to play on your own these days than back when I learned. The internet has a lot of good instructional materials available.

Here is a link to a series of video lessons. These may help you get the basics down better. This guy has a series of 12 video lessons at Youtube. He covers the basics pretty well. You can find the other lessons in the related videos section there. He uses an electric in the lessons, but most of the material translates well to the acoustic.

Just in case you have not already learned how to read tabs, here is a link to an article that explains them.

This one is a chord chart. Down load the PDF file to your computer. Then you can look through it for various ways to play a chord.

If you want to learn some songs, you can do a Google search using the song name and the word tabs. That should give you like to places that have the guitar tabs. Those will be places like 911 Tabs, Tabs.com and others. You can also use the search feature at Youtube to find lessons for particular songs. Search the song name and the words how to play or the word lesson. There are a lot of good instructional videos available on Youtube.
