Web application frameworks are fine for simple user interfaces. For more complex UIs, you want a desktop UI framework. Or you can try Rui.
Perl Rui is an open-source UI framework, designed for browser based applications with a rich UI. Smalltalk-style MVC is supported. Download from the Rui homepage.
Here is an example with a list view and a text field. The text field displays the item selected in the list view: 
$model= Rui::Model::SelectionInList->new
   (data => [map {"Item#$_"} 1..10]);
$field = $self->TextField
   (adapt => [value => $model->selectionHolder]);
$self->List->model($model);
