Was this done with blogging software or webdesign?

I know that sometimes there is a fine line between the two.

I want to make a blog/webpage that is more of a magazine format with ongoing columns, i.e. each month I will write an article about my own life, each month about the children I work with, the Chinese word for the month, etc. If I could find out how to make the page shown in the link I would be a happy camper ??

Thanks for any input.
