super minimalist plugin for MS Project: where to get started?

I was wondering if you could point me in the right direction as far as developing a super simple plugin for MS Project (both 2007, which uses the old style ribbon, and 2010 which uses the new ribbon). What I need to implement:

• create an executable that installs a new button, with a specific icon, in some per-determined section of the ribbon

• when the user presses the button MS project needs to save a file in a specific format and location and then call a batch file.

that's it - pretty basic, right? Turns out, I know nothing about this space - so apologies in advance for how trivial this may be. Note: I'm not tied to a specific language - whatever is simpler / faster开发者_如何学Go will do.

BTW, does anyone sell components like this one? I don't necessarily need to code this if there's decent stuff out there for sale.

thank you!
