now, it seems to me that the project: https://github.com/chrisburel/perlqt give this perl porting another puff of smoke...but it is not the glossed item yet. one can code...

use PerlQt5::QtCore;
use PerlQt5::QtGui;
use PerlQt5::QtWidgets;

package MyApp;
use base qw(PerlQt5::QtCore::QCoreApplication);

package MyPushButton;
use base qw(PerlQt5::QtWidgets::QPushButton);

package main;
my $app = MyApp->new(scalar @ARGV, \@ARGV);

$app = PerlQt5::QtWidgets::QApplication->new( 'Hello, World!', undef);

# but crash here with error ... QWidget: Cannot create a QWidget witho
+ut QApplication
my $button = PerlQt5::QtWidgets::QPushButton->new( 'Hello, World!', un
+def);

yes, I am noy sure how to instanciate a global QApplication ?
