Run Apache not as service ?

Hi,all

I am a newbie here and kind of need your help :)

I set up my Apache server and perl under WinXP,everything ok. Then I
write a CGI script that parses some form information, and then spawns a
win32 application.

#!/usr/bin/perl
use strict;
use warnings;
system qw(start c:/windows/system32/calc.exe);

Now I can only see calc.exe running in task manager,but it is not
visible on the desktop. I think the reason is that since the Perl
script is running on the web server, the web service
needs to be allowed to interact with the desktop. But how to make it ?

Any help appreciated !!
