There are a number of online services that will help you create a blog within a matter of minutes, such as Xanga, but these come with the down-side that if you want it to be ad-free, you're likely going to have to pay an annual fee.
An alternative is to use a CMS like WordPress or a watered down Joomla installation. These are free of cost and pretty easy to install if you have easy access to the tools necessary to create a database (preferably MySQL). These are generally pretty simple to administer though you'd find that with a little time spent searching, there's actually a lot of really good documentation for more popular CMS and "blog" applications.
I really don't know a hill of beans about blogs either. I thought a blog is just a plain text file which is posted on someone's web site, such as DaniWeb's blog board. You could write it with Notepad.exe (on MS-Windows) if you want to.
Or, is Garud actually talking about how to create a web site that supports blogs ??
