There is a great post up on Techsnot (yes, a somewhat unfortunate name :) on how to install Wordpress on a Mac in under 5 minutes using the BitNami Wordpress Stack. Although the author (‘dogsnot’) installs the Stack on a Mac, the steps are the same on Windows or Linux. In a future article, the author will explain how BitNami Modules work.
If you are using BitNami and want to help us out, writing tutorials like this is a great way to contribute. Thanks to Dogsnot for his article!
