Hello friends, I needed your help to modified the gctrl (g-code sender for CNC Machine that use Arduino)

Yesterday, I found very useful and interesting g-code sender that build on Processing, develop by damellis (David A. Mellis)
I already test the gctrl g-code sender on my CNC Machine, it's run smoothly.
I found it here: https://github.com/damellis/gctrl



I made a decision to make little modification, by adding GUI on the gctrl g-code sender.
this is what its looks like:



but, I have these problems, I hope members can help me how to make it done:

1. How to show file name on the Processing, the location is after "File name:" as shown on the picture above.
2. I have run the g-code sender and the running g-code is shown on the Processing text area. Is it possible to show the running g-code on the interface, the location is on the box below the "File name:" box as shown on the picture above.

Pre-compiled gctrl (macosx-32bit): http://www.mediafire.com/?epu2qcbhamwpp6t
Pre-compiled gctrl (linux): http://www.mediafire.com/?cd5y2gyyh7uxfbt
* I'm sorry I only have Windows OS, its run smoothly on Windows. I hope members can help me try on other platform.

I hope forum members can help me on solving these problems.
I'm sorry still learning tough.

Thank You and Regards,
