Stand-Alone Computer Application Language?

[indieFan]

Hi Everyone,

I am trying to come up with a stand-alone computer application at my job that will give the user an interface to enter which files to use (up to 4 right now) and work with Excel data and PowerPoint for the final output. Can someone please suggest which programming language I ought to be looking at?

Currently I'm looking at VB.NET. Does anyone have any experience with deploying a stand-alone computer application at a major company? Was it a problem?

Thanks for any information.
