Create SharePoint Business Checklist

Hi
Let me qualify this by saying I am still fairly new to Sharepoint with background in Java programming. I need to create a form for users to complete a checklsit of tasks that are undertake on a daily basis. The user completing the form will put their name or initial against each individual task. User log in details cannot be used to track who has completed what action because there is only one individual login into Sharepoint for each site.
The form will be something like this :

1. User will "Select week number"
2  User will "Select day of week)
3  Tick/Enter their name/initials against each individual action/task e.g.

           
                                                                                             Checked By
Accounts
Invoice date check                                                                 joe bloggs
Quantity ordered correct                                                      Any name
Goods recieved note attached                                              John
Requisition raised                                                                 Wills

Goods In
Goods received in good condition                                        xxxxxxx
Product in correct location                                                   John


"Accounts" and "Goods In" are departments with respective actions that have to be checked by users on a daily basis.

The checklist will sit in each individual "site" documents and also accessible via a link in the quick launch menu.

Checklis is being done in SharePoint 2007.
