One word of advice: patterns are not holy. Don't try to force your code
into a pattern. Even if an existing pattern would be appropriate, you
might choose the wrong one. Read about patterns and see _why_ they are
useful. You may very well come up with a number of patterns of your own.
Some programming languages even create a need for them.
For me, patterns emerge from my code. And as my code is not that unique,
many patterns are recognizable from textbooks as well. Reading about
patterns helps you to identify them if they emerge. But if they don't
emerge, no problem.
And do not be afraid to change things later. No program is perfect and
even if it were today, it wouldn't be tomorrow. If I may suggest a good
read, read "refactoring" by Martin Fowler. It features a nice "let's put
a class statement around this" program and it shows how to morph it into
a real object-oriented one.
Good luck,
