If the Gtk::Text widget is the only thing in the page then
$notebook->get_current_page->child->insert(...)

else if there is a Gtk::VBox or Gtk::HBox that holds only one Gtk::Text
for my $child ($notebook->get_current_page->child->children) {
        if (ref $child eq 'Gtk::Text') {
                $child->insert(...);
        }
}

else if there is a Gtk::VBox or Gtk::HBox that holds more than one Gtk::Text
then you need to attach data to the widget so you can find it again

my $text1 = Gtk::Text->new;
my $text2 = Gtk::Text->new;

$text1->{name} = "first"; #perlish way
$text2->{name} = "second"; #perlish way

$text1->set_name("first"); #Gtk way
$text2->set_name("second"); #Gtk way
.
.
.
#perlish way
for my $child ($notebook->get_current_page->child->children) {
        if (ref $child->{name} eq "second") {
                $child->insert(...);
        }
}

#gtk way
for my $child ($notebook->get_current_page->child->children) {
        if (ref $child->get_name eq "second") {
                $child->insert(...);
        }
}
