Perl Curses::UI

Question

I am trying to use the library Curses:UI from http://search.cpan.org/dist/Curses-UI/ to build a UI on linux karmic.

I can create a simple user interface e.g.:

#!usr/usr/bin/perl

use strict;
use Curses;
use Curses::UI;

$ui = new Curses::UI(-color_support=>1,-clear_on_exit=>1,-intellidraw=>1);
my $window = $ui->add('window', 'Window',-intellidraw=>1);
my $message = $window->add(-text=>"Hello!",-intellidraw=>1);
$window->focus(); 
$ui->mainloop();

Question: I need some way to communicate informatio to the UI i.e. I have a loop which will wait for message to come and change the text in window. Once this message comes a popup will be displayed. Attempt:

my $ui = new Curses::UI(-color_support=>1,-clear_on_exit=>1,-intellidraw=>1);
my $window = $ui->add('window', 'Window',-intellidraw=>1);
my $message = $window->add(-text=>"Hello!",-intellidraw=>1);

pseudocode
while(true) #implemented a function to wait
{
    popup($window->text("Hello how are you?"));
}

$window->focus(); 
$ui->mainloop();

Problem: The above does not work. I am given a dark screen where my message is displayed. I have read the documentation and when I relocate : $ui->mainloop() above the while loop I am given the user interface but now nothing communicates to the window.

Coincise Question: I need some way of displaying the user interface wait for inputs and display messages.

Could anyone please help me on this? Thank you!

Could you please let me know how do I do the update of the frame (Problem which I specified above) with Wx Perl. As far as I have understood I still need to call mainloop in Wx for the GUI to appear. Just guide me please. Thanks.
