How to go about developing in zope

[john]

Hi
I am developing a timesheet system.
It will have 3 levels of access 
1)Administrator
2)Approver -- Will approve or reject the timesheet filled by employees
3)Employees -- Fill in the timesheet which will ontain info like start
time & end for task & task description.
There will be different projects with different employees & approvers
Also I need to genrate reports like timesheet for an employee for this
particular week or month.Or timesheet of a project etc..

Is zope suitable for such kind of application?
I read the zope book & now I am more confused.
What is the best way to develop such kinda application in zope?
