To start with, Linux offers 'too much choice'
A few years ago, I would recommend Ubuntu to new users
These days I recommend Mint..
Mint is 'based on' Ubuntu, which in turn is based on Debian.
( although there is a more Debian like Mint )
But don't worry too much..
If the desktop is not to your liking you can install a different one
For instance desktops like lxfe , xfce, mate have a more 'traditional' interface
Ubuntu / Mint
Go for an LTS (Long Term support) version, at least untill you find your feet.
Might be worth trying a few distos in something like vitualbox
Or simply burn a few liveDVDs and have a quick look and get a feel for the different interfaces
If you have trouble 'burning' a cd/dvd on windows, I;ve found wincdemu very good
Right click iso -> burn
