I would say leave CGI::Application alone until you improve your understanding of OO programming. What tutorials have you tried?

Have you looked at

Obviously, don't just read. Write code and experiment, that's the best way to learn. OOP isn't that hard, and is well worth learning.

Update: BTW, the approach you are already using is very sensible. Here is one way to break out the run-modes (untested): 

use strict;
use CGI; # or CGI::Simple

my %dispatch = (
  runmode1 => 'My::Package1',
  runmode2 => 'My::Package2',
  runmode3 => 'My::Package3',
);

my $rm = $q->param('rm');
eval "require $dispatch{$rm}" or die "runmode handler not found";
$dispatch{$rm}->handler($q);

In each package create a sub called handler that looks like: 
sub handler
{
    shift; # ignore 1st arg (package name)
    my $q = shift;
    ...
    # do what ever runmode requires
    # return html output
}

May the force be with you :)
