I developed applications in php, and delphi. now i want to write a plugin /
addin for outlook. it seems totally different. delphi generates an
executable file which i run on command line; php i can start in a browser.
and for outlook addins/plugins? can i do it just with php or delphi??? or
must it be done with vb, vba or java?


I want to write a program that generates an icon in the outlook toolbar.
clicking on this icon a menu appears.

when sending or receiving an email, something should be executed (eg a
beep).

Where can I find example code for the two goals above? how can i run the
code? do i need a special development environment?

at the end, the program (plugin/addin) should be installed very easy and run
on every newer version of outlook.
