Request for a basic framework to create new feature

I want to create a new feature but have no idea of how to write the code. Since webissues have it own framework, it had took me few weeks to understand it while i'm quite new to this object oriented php. Now i have php file created under folder "client" but i dont know how to link the code in order to make it work as a page. I wonder if someone would show me the basic framework to create it?

Here is some info about my idea, if needed:
In the Issues page after log in, I wanted to create a feature to view the statistic for the "All Projects".
In this "View Statistic" page, tables will show the "Issues" with the "no. of submission" by "who"
For example,
table 1
_________________________________________
| Type of Testing | No. of Submission | Submitted by |
|____________ |_______________ |___________ |

table 2
______________________________________
| Defect Type | No. of Submission | Submitted by |
|__________|_______________|___________ |

This page will display all the tables depends on the issues i have in that project
