file converter

Hi guys Im a researcher and not a great coder and I need help on something.

I have created a c++ program that converts a file called .nxs (nexus) to a file cslled a .med (mega) … This works in dos and is real simple..

I would like to add this to my webpage now.
Im thinking along the lines of creating a VERY scaled down version of this site .. hxxp://www.cbs.dtu.dk/services/TargetP/

For example , browse for file, hit submit… and BAM pingo
either a window comes up asking where you want to save this new file or a new http window popup with the new file in txt format for ctting and pasteing onto notepad.

btw both file formats are very simple txt notepad text files that have slightly different formats.. we just usually edit in notepad and save with new file extension…

this is my C below to give you an idea of what im doing..

thanx guys
brian
