first of all im sure you know you need your own person webspace. you could then use a program such as CoffeeCup that lets you use HTML code and Visual code. put all the files you want to use for your website in the same folder. create a new file in CoffeeCup and name it index.htm or index.html. then you just need to insert a link to your mp3 file or whatever it is you want. then you need to get FTP. download a basic version if you can, as the complicated ones just discourage you from going any further and "upload" all the files from your folder into your personal webspace.

im not sure which of parts of this information you need so i just gave you a full short guide on how to create a website.
im sorry that this is not too detailed but its all i can do at the moment.
