You remind me of one of my boss. He wanted similar things. In fact he felt I (programmer) was unnecessary as a project can be completed with drag and drop, download code / library etc. by anyone !
Well, I can tell how he proceeded with few of his men.
VB.Net was selected. Biggest merits :
1. Programmers available in thousands, nearly every student of Computers knows it.
2. Internet is full of code of VB.Net, Stack OverFlow, Code Project etc.
3. Lots of Libraries on it are available some even free.
4. You got the idea.
I do not know VB.Net, but the project is still not complete. Reason, he put cart before the horse.
My advise, first decide what you want to do, then look for the hammer. The same hammer can not be used to fix a broken old chair and a broken gold chain.
DC is full of programmer with extensive knowledge in VB.Net (yeah), Delphi, C++, Autohotkey, PHP, Java, you got the idea
