Nice tutorial but for those who are not techy enough just use the fantastico installer (one click auto installer). Its great with this server coz it automatically creates a database for you, so you need not to worry: how to create a database or alter wp-config file coz its all there.
Upon one-click installation, ALWAYS read the instructions there. And when you are asked to fill up username & password for admin purposes take not of that. Coz that would be your username & password when you login to your wordpress dashboard.
After the installation is finished, to login just go to yours site, example:
(if you installed it on the root folder)
Then just enter the username & password that i told you earlier to take note. That's it
