Dreamweaver??

Hi friends,
I may sound a bit daft and utterly lost as I am a newbie to PHPs. After installing W.Press in my computer when i unzipped the files the php files list showed dreamweaver logos as i have D.weaver installed in my computer. when I click on those php files —the D.weaver opens. What can i do about this?? as I need the dreamweaver as well.

As per intructions i have renamed the file to – wpconfig.php
My SQL database (host 1&1) has created 4 database instead of one — dunno why??
I have downloaded a text editor to edit config.php (yet to do).
I use Filezilla FTP , should i upload all the W.Press php files individually?
I have heard so much positive about WordPress I hope i will be able to make a website using it.
Please help!!
