I’ve heard of people using WordPress to create their page. How can I use this program to do it?
WordPress is a content management system. If you install it (see One-Click Installs if you want to do that), it allows you to maintain a web log (“blog”); however, it is probably not the best choice of blog CMS for a web novice because it assumes you understand at least some HTML and CSS (the languages of the web). Any CMS will essentially create an entire site, not a single web page.
If you are just looking to build web pages, you may be thinking of a WYSIWYG editor.
