How hard is computer programming / how do I go about it?

[mrsurrey]

Hello,

I've created lots of mysql/php websites using relational databases and I'm happy I can scale them pretty much infinitely. I'm wondering how much harder it is to create computer programs (for Microsoft operating systems)....

I have a very strange burning desire - I want to write a computer program that addresses all the shortcomings of Pivot Tables in Excel, for a particular niche that I work in. Basically it will be like a Microsoft Excel workbook with a Pivot Table - one sheet holds the table of data, and the other sheet holds the Pivot Table.

So how hard do you think it would be? And what computer language should I use?

Thanks,

MrS
