gtk app without mouse and keyboard

[Bureau d'études terawatt <be terawatt wanadoo fr>]

Hi all,

I 'd want to build an embedded system interfaced with gtk, but without
any mouse or keyboard. I have just a few keys raising interrupts. Is it
possible to trigger by software the widgets signals normally raised by
mouse  ? (and how ...) And in the same way  is it possible to select the
widgets (as done by the tab key) ?

thank you for helping a newbie...

Regards,
