I actually disagree. There's a big difference between reinventing the wheel - which happens because you didn't know that somebody else had thought of this before and already solved the problem - and building your own wheel because none of the off-the-shelf wheels work that great for your needs. If this is a small business website and will never be built on ever again, then absolutely ignore the hate and go Wordpress. If it's something that might be extended over the years into use cases beyond just a webform to post an article with a title and a body then it's worth evaluating if you might be able to custom tailor a better fit for your business.
