R – Send an e-mail based on Workflow approval status using Sharepoint 2007

I am new to sharepoint. I am using sharepoint 2007. I have a following requirement.

1) Custom list has various fields … Requestor, Application Name, Reason, etc..

2) When person fill out the form (custom list). It will send a notification to Approvers for review and based on Request action : Approved –> It will send an e-mail notification to specific group.

I have a setup a document approval workflow on custom list. Workflow works fine but I don't know how to send an e-mail notification based on workflow status : Approved. I have tried to create a another workflow using Sharepoint Designer 2007 but didn't work.

I would like to know whether it is possible without doing any programmatic way ? I would appreciate your reply.

Thanks in advance.
