Looking at your previous posts, this seems to be a question you've asked before, with, in fact, an answer there that seems to have spawned the question you've asked here.

In my opinion, if what you're doing is valid, there are better, more reliable ways of achieving something like this. Remember that the Windows Messaging service isn't guaranteed, and, more and more often, especially on corporate machines (at least where I work), it's been disabled because of security/spam problems with it. In addition, popups like these will get blocked by any half-decent desktop firewall. If this is something business critical, I'd suggest e-mailing or paging/SMSing your clients, both of which can trivially be achieved with Perl.
