I’m not entirely certain I understand your question, but I’ll try to respond.
It will depend upon which template you’re using for your WP blog, but for the most part, your title is automatically placed into your page based upon the name you gave your blog when you ran the installer.
Of course you can always edit the index.php file of the template you’ve selected to make changes to how and where the title of your blog is diplayed.
If you’ve only done straight html before, then php may be a touch confusing initially. If this is the case, then it might be best to just go with an existing template and poke around in its files to get a feel for how things fit together.
