Small short example in GTK+

["Petr Hracek" <phracek terra cz>]

I am a begineer in programming grafical interface over GTK+.

I would like to ask you if you can write me one program with source code
which will do following.
On the main dialog will button, edit box and List box.

If I bush on the button than text from edit box will be added to the List
Box and
after adding text to the list  will be opened new dialog box.


Thank you very much for your time

If I will have a small example than other steps will be easy. I need really
help.
Best regards
Petr.
