Im pretty sure that this app is written in C... but not 100% !!!
The app was written for me a while back via Scriptlance but has never work correctly... If you can fix it the job is yours...
OR.. If you would rather remake the app in whatever language you choose that is also fine.. but the money available is the same.
Maximum available for the project is $15 or $30 if building a new working app from scratch !!
Details of the original project can be found on scriptlance, project number "1163817718". Please ask if you need further details.
