David,
A website might be the best way to go. They're not as difficult to create as you might think, although I'm still learning. Many companies offer templates for websites, so you pay them 10 or 15 bucks a month for hosting and they give you all the tools you need to creat a pretty nice looking site. Thats what I did on my site:
www.jimi-michiel.com
Hope this is at least a little bit helpful. Good luck with the composing thing. It's great that you're taking an interest in a non-performance aspect of music. The more you can learn, and the more well rounded you are as a musician, the more you will enjoy and love making and listening to music.
Best wishes,
Jimi
