Do I have to use Perl?

No - you can use any programming language you please.   Perl is simply
today's most popular choice for CGI applications.   Some other widely-
used languages are C, C++, TCL, BASIC and - for simple tasks -
even shell scripts.
Reasons for choosing Perl include its powerful text manipulation
capabilities (in particular the 'regular' expression) and the fantastic
WWW support modules available.
