I work on a daily basis with Java/Swing c/c++/python both on windows/linux/solaris on a professional level so I'm quite confident that I can do your project.
I'm bidding very very low but my work speaks for it I'm on freelancer to get reputation a go on to bigger projects. So basically it's all about reputation /good feedback right now, I really don't care about (that much) money.
Give me the change and you wont regret it. I do need clarification about which language is to be used, the hosting location of the bot and more details about the bot itself.
I can do it quite fast but do please send me the deadline, i can start ASAP.
