How to secure non-wordpress pages with wordpress login

i have the latest Wp installation.

suppose i have a site http://www.mysite.com inside it i have a folder “myExamples” and the folder contains php files and other webpages that i want to make secure..

so if someone types http://www.mysite.com/myExamples they should be given a login form by WordPress after successful authentication they can access the contents?

Possible in Wp or do i have to hand code the Auth form in php??
