mGTK progress

Tonight I decided to try and port an example from Mono: A Developer's Notebook to the upcoming release of mGTK.

By joining forces with Henning we were able to compile the example for the following screenshot:

The email entry-box is updated dynamically when you type something in the two other entry boxes. Mnemonics works, that is, if you press ALT-f the focus jumps to the entry-box for the first name and the text is selected. And all that in less than 100 lines of SML code.
