Customization for Email Notification and Pop-up Screen

Hi Experts,

We have the following requirements.
Wondering if anyone has done =components of this development or has ideas as to how to create:

When category = Actual & work status = Approved by manager (owner and manager can execute Data Manager Activity), each time the import from BW DM package is executed two events occur:

1. A pop-up box appears to the user (owner) where (s)he can use free text to record the reason for a new import.
2. An email is sent automatically to the administrators notifying of the import and including the explanation text documented by the owner.
3. This free text would be available in a report for later review.

From initial review, there are process chains that execute the import, and presumeably we would need to add an event to send email
notification to a pre-defined list of people.  How to trigger the free-form box and include it in EPM is not clear to me.

Any ideas?

Thanks.
