I agree with Rob here, but as always there's a little more I can add. I would say that, if you want to learn how to make web pages generally and you think that you will make more in the future, then taking the time to learn HTML and maybe CSS too is definetly a good idea.
If, however, you think this will be the only website you will ever make, then there may be little point in your taking the time to learn HTML - Maybe you should stick to an editor to do it for you. The choice of course is yours.
Alternatively, if you don't want to spend money on an editor, you could use an online editing tool to help you... Sites like Geocities allow you to construct a website visually, over the internet. Of course it doesn't give you much power or flexibility, but if you want a quick and easy website and you don't think you'll need to make a website again then it's certainly not a bad idea.
