Purushotham,

I strongly recommend looking at the gok function 
"gok_output_send_to_system" which is located in gok-output.c

Specifically you might be interested in SPI_generateKeyboardEvent which 
is documented here:
http://developer.gnome.org/doc/API/2.0/at-spi/at-spi-cspi-Registry-queries.html#SPI-generateKeyboardEvent

This is API that allows the use of the at-spi library which has been 
developed by the gnome accessibility folks with lots of help from Sun 
Microsystems (or is it the other way around?)  It is a powerful library 
that is maturing well.

If you want to send keyboard events to other windows you will want to 
make sure that your window doesn't take focus... let me know if you need 
help with that.

cheers,

David
