This is really a user interface issue and the standard user interface is different between platforms. Would tcltk (or RGTK or ...) be a possible solution for you? tcltk is fairly consistent across platforms and does provide for this type of thing (you can have a button to press to continue and use the after function to send an automatic push if the user does not push it before a given time).
