Trigger a workflow using a custom menu item

System

Hi Community,

We have a requirement that should call a particular workflow model when a user clicks on a custom menu item (Say Publish xyz report).

My queries are around the following areas:
1) What would be the best approach to call the said workflow from the menu item? (Like : Should i write a JSP or a servlet that would internally do the workflow calling logic?)
2) Has anyone done such an implementation? I have read the forums on WFM initiation using CSSDK but havent found a similar situation to mine.

It would be really helpful if a reference to any documentation or code snippet to instantiate such a workflow.
