I'm an engineering (electro-mechanical) grad student with limited programming experience.... However, I'm trying to figure out a way to read experimental data from a serial device (analog numbers and sample time), save the data to a file, and then upload the file to a server. I'm thinking that the data can then be viewed and plotted on a website with some javascript charts.   

I need to build an app (that can be shared with others, e.g. .exe) that can read the data and upload the file. It would be nice to have:

-- a good-looking gui with buttons to start/stop the data recording, 

-- and plot the data streaming in (to make sure there is a signal). 

I've written an initial script in python but the gui and real-time plotting is difficult. Someone suggested processing. Is this the way to go, or should I try something like C#? I'd appreciate any tips to get started...

thanks!
