I'd like to create an application that has as window,
a pushbutton and a text field. Upon pressing the button,
"Hello world!" should be displayed in the text field.

Ya know, for testing projects, windows, widgets and 
binding to code.

Is there a tutorial on how to make such a 'dialog' app?
I find Squeak much more confusing than other Smalltalks.

Cheers,
Richard
