Need suggestions about coding MSN bot

I want to code an MSN (Windows Live Messenger) bot that automaticly sends info messages to the users of my forum from msn. But i couldn't find where should i start first. There are some Windows Live SDK's but i don't know which one is suitable for my project. I don't know how to connect Windows Live Server and use its packages. I prefer to code it in PHP but i can also code in Java, Javascript or c#.

Can you help me and give me some some reference?

Do you have any suggestions for executing commands like

CVR 2 0x0409 win 4.10 i386 MSNMSGR 6.2.0208 MSMSGS [email protected] OR
USR 3 TWN I [email protected]

without using any third party software? Is there any way to use MSNP commands in PHP or should i have to use c# or java libraries and write the codes in those prog. lang.

Sorry, but you'll have to use a3rd party framework with any language except for Microsoft's C#.
