Looking for quick solution on removing the background of this Photograph. Any relevant suggestion?

I'm really passing a tedious moment to solve this quest. I have seen few tutorials but all those seem to be very difficult for me. I dont know why. As I am not a tech savvy guy. In my Pro surfer, i've found that the Photoshop7 is already installed. What to do now :unhappy:. Any relevant help?
