Win32::GUI has a function to minimize a window. The tricky part is finding the window you want to minimize; it might not be the only window in the application.

use Win32::GUI;

my $title_part = shift;
my $class_part = shift;
$title_part or die "Supply title substring\n";
$class_part ||= '';

my $perlwindow = GUI::GetPerlWindow();

for (
    my $window = GUI::GetWindow( GUI::GetDesktopWindow(), GW_CHILD );
    $window;
    $window = GUI::GetWindow( $window, GW_HWNDNEXT )
)
{
    next if $window == $perlwindow;
    my $title = GUI::Text($window);
    my $class = GUI::GetClassName($window);
    if ( $title =~ /$title_part/ and $class =~ /$class_part/ )
    {
        warn "Minimizing $title: $class\n";
        GUI::Minimize($window);
    }
}
