The term 'easy to install' is relative.
I've installed most distros over the years and some I would consider fairly easy to install could be classed as difficult by many users who are used to installing Windows.
If you want an install process like you get with Windows and an OS that looks like Windows and is used like Windows, I recommend that you take a look at Xandros OCE.
If I remember correctly, it installs in around 15 minutes with just 4 mouse clicks, can go onto the internet straight out of the box and can see Windows networks and shares without any configuration.
With software called Crossover, it can even run Windows software like MS Office and Adobe Photoshop.
