CarysL on "Install for me?"

I'm so lost! I've been trying to install wordpress for days, and I'm just not getting anywhere with it! I got as far as trying to setup the configuration file, but it won't recognise my details. I hadn't set up the wp-config.php file so I tried that and still nothing! I'm only sixteen, so I don't really know very much about all this stuff. My website is hosted by BT, I should've got one of the recommended ones but I only found out that I could do this after I'd set up my host. Could someone please help me, I'd be really grateful if someone would offer to install it for, if that's possible?
THANK YOU!!
