Hi Karlina! If you are just interested in an easy starter, then you can use a template. Almost all hosting packages contain online template editors with pre-built templates and you can also dowload whole free template packages from great sites like http://www.oswd.org
Of course, you will need to edit the downloads; I suggest using Seamonkey - http://www.mozilla.org
it is free, has a GUI interface and is great for learning basic HTML. You can also buy pro packages like Dreamweaver, but I think that is overkill. Let me know if you need help!
