There's an abundance of guitar information out there on the web, some good, some not. I stumbled across Justin Sandercoe's site a year ago and now tell everyone about it. The lessons are conveyed so clearly, concisely and in the most congenial way. The site is laid out logically as well so you can to go straight to your area of interest... beginner, blues, rock, folk, jazz, rhythm, fingerpicking... it's all there and more. Spend ten minutes with Justin and you'll not only play better but feel better too. From novice to know-it-all, everyone will learn something from Sandercoe.
Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
Strum your guitar with a pick or your fingers. Hold down the strings with your fingers in the appropriate shape and try to strum with your other hand. Acoustic guitar strings often have higher actions than electric guitars, so you may have to press down very hard to get a good sound. If the chord comes out muted, try holding down the strings with more force. If your string is buzzing, move your finger further away from the metal fret on your neck.
I have checked out Justin's site and found it to be comprehensive and informative. I have always felt that learning about music and especially music theory applied to the guitar, is helpful in finding your own unique voice on the instrument and expanding your creative horizons. Along with his insight into teaching and his fantastic abilities on the instrument, Justin has created a powerful go-to-place for anyone interested in exploring the instrument to their potential. Just don't hurt yourself.
I know that for me, I enjoy getting to put the spotlight on my students. I also like haveing concerts for my students to be able to demonstrate their skills for their friends and family. I also can work with students of any age, starting at about age 5 through age 100+. My experiences with teaching children gives me the ability to teach even very young students.
Learning to play the guitar is a life-long process; it will not happen overnight despite what many of the hucksters on the internet may tell you. As such, you are best to develop some reasonable expectations of how quickly you will progress. There will be challenges along the way (yes, your fingers will hurt!) and too many budding guitarists have given up prematurely, slid their brand new guitars under their bed, and walked away in disappointment… not realizing that they were oh-so-close to a breakthrough that would have taken them on to the next level. Having a mindset that allows for setbacks here and there will really help you in the long run, because you will find that through every challenge you come out a stronger player on the other side.
I tried several times over the course of 20 years to learn guitar. I purchased guitars, amps, books, private lessons. Nothing ever stuck, until I found justinguitar.com. The only reason I can play guitar today is because of Justin. His courses are well thought out, easy to understand, easy to follow, and easy to make progress on. I can't think of a single product or service that I've ever used in my life that I could recommend more highly than justinguitar.com.

If you just want to learn a few chords to strum along to some songs, then learning to play the guitar really isn't that hard for most people. Many students are able to learn a few chords and get a decent strumming pattern going after a few weeks. If you've had prior experience playing an instrument, you can expect to pick it up after just a few lessons.
