Never forget the content of the website is the most important aspect of the site.
The question is do you need a dynamic WordPress blog site or a static HTML website?
If you have a lot of content and you want to update the site by yourself choose a blog site.
If you need only a few pages and you do not want regular updates then the website can use static HTML web pages. Pay attention this though; if you need to make any changes and updates on a page, either you will need a web designer or you can do it yourself if you know HTML language. With a Dreamweaver, CoffeeCup HTML Editor, Notepad ++, FrontPage or any other HTML website editing software can be helpful to do updates.

HTML vs PHP
If I want to explain as simple as possible I can say this; HTML web sites are static, a designer or a person who knows HTML language can update website with a ftp program.
On the other hand a blog is done with php like WordPress, it can be updated without needing a program or designer by the site owner.
What are these terms means? HTML is the code required for a web page to show up in your web browser; PHP is the code that changes the HTML code.
