Problem while creating custom plugin

[dominionit]

Hi,

I want to create a custom plugin which works like this

Admin :
1. Click on add profile
2. Fill the form
3. Save [ Save into Mysql database]

Front End :
I want to populate the data on front end

Problem:

How should i create a custom plugin for the new version of getsimple... is there any tutorial guide or a post.
1. I edited the sidebarfile in admin template,
2. Added the menu i wanted to and uploaded my php file inking into the sidebar anchor tag but when i click the link ...... it shows me 404 error saying this page does not found.

Please let me know how i can create a plugin stated above with admin panel because population of data will not be a problem for me i think so.

Looking forward to hear from Admin or any other expert from the forum...

Thanks
