Subject: Beginner's question

This question may be a bit too "simple" for this forum which seems to
target intermediate and advanced users, but if that's the case someone
could perhaps direct me to a place which is better for asking this
question?

 I have just recently decided to try and learn programming (namely
Ruby), and in order to do so I've been using a tutorial called "learn to
program" (http://pine.fm/LearnToProgram/).
 Everything has gone just fine until I reached the 6:th chapter (Flow
Control) in which the author teaches about among other things branching
and loop-methods.
I think I understand most of it, however, I'm having very large
difficulties with the " A Few Things to Try" part of the chapter.
 I find the "99 beer bottles"-program utterly impossible to do. I
realise that I should somehow use the methods listed on the page, but I
just can seem to know how. My initial idea is to create a variable
called "bottles" which at first is 99 and then subtract 1 in every new
verse until the variable hits 0, where I was thinking I could use the
"while"-method to end the program. Each new value would be inserted into
the lyrics. It would look something like this I suppose (please don't
laugh, I know it doesn't really do anything at all).

bottles = 99

while bottles != 0
# Need help here.
end

I stumbled upon a site which showed how one scould program this in Ruby
(http://99-bottles-of-beer.net/language-ruby-1272.html), but the problem
is it doesn't use the same methods. It's more advanced since it creates
classes and defines methods, something which I think lies a bit too far
ahead for me, and I somehow want to learn things in "the right order".

I'm thankful for any tips as well as code-examples. Thank you very much.
