just install the latest version, and put your website in the www folder on your computer, then you can access it via
http://127.0.0.1/
if you want to let the rest of the world access it you need to modify the apache settings and thats not too hard:
once its installed and running right click on the icon in your system tray, go to: configuration >> apache
look for:
code:
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, in addition to the default. See also the <VirtualHost>
# directive.
#
#Listen 3000
Listen 127.0.0.1:80
enter "Listen", your own ip address, then ":80" right below that line
save the file and your done, every body should now be able to view your site from your ip address
edit: if you're behind a router, see my post below
