The form submission must be handled by a CGI script on the server, be it
Per/PHP/Python/etc

Thats pretty much what I was alluding to in my earlier post regarding this.
Except I am sure the are Perl modules already built for decent template
handling,  but simple find & replace of fields work 100%

In what way? You mean variables you calcuate in your example script, and
want to part of the links in the template you print? In your HTML template,
simply make a "variable" that will be replaced by the caculated value:

[htmlpage.html]

<p><a href="go_to_this_page.cgi?my_value={something}">Click here</a></p>

[in cgi above]

$something = calculate_it();

....

$html_output = s/\{something\}/$something/gi;

....

print $html_output;
