The question has been is there a way to change the wp-admin

The question has been is there a way to change the wp-admin login without a plugin there is inside the includes these although I did get to a login page and was not able to login.Is there anyone who knows how to change this I would imaging in the joomla it maybe be easier I am not sure.
I like wordpress although I am not setting up anything else unless I can change these options without a plugin.
If someone can help me tell me were to post this to the job board I will pay someone for directions to help me make a custom login hackers and bots are driving me crazy trying to login by the hundreds daily to http://www.fluffey.com.
