Help with auto-adjusting text inputs within a boundary

Help with auto-adjusting text inputs within a boundary

I have the following codes:





















I want the above to display so that the text input always take about
85% of the bounding box, the browse button take the remaining 15% and
I also want the submit button to be always at the bottom right corner.
Any help on how to accomplish all that?

Thanks,
Thierry
