How to create and Admin Panel for my website

I'm having trouble wrapping my head around on how to create an admin panel for a website.

I recently installed the CK editor to the website and and am having a problem seeing the edits -when I made a change to the test page and hit submit changes I then looked at the test page and did not see the changes . But after installing it I noticed that I could only edit one page and that was all. What I want to do is have a page admin where you can see every age of the website and add pages to already existing pages and so on. I have done this in the past, access this sort of page admin, not create it. And now I would love to learn how to do this myself. It was coldfusion that the page admin in the past was running on. And they used the fck editor to edit the pages of the website, create new ones and so on.

Please if anyone could be of assistance that would be wonderful. Thank you in advanced. And I know I have two problems here so if anyone could help with either of them I would be thankful.
