I suggest renaming 'OK' and 'Cancel' buttons labels (in the main dialog), as they are not intuitive right now. They should name the actions which are really triggered by these buttons click:
'OK' -> 'Generate'
'Cancel' -> 'Close'
I would especially vote for renaming 'Cancel' button. After each successful icon generation user is navigated back to the main dialog. Only way to close it now is clicking 'Cancel', which is usually associated with resign action. In my opinion 'Close' would be much more intuitive here.
