How do I use custom Windows/Forms?

Question

Hi, I wanted to know how to use a custom window/form for my programs... With title bar different from the normal one and incorporate the minimize, maximize and close buttons on them, possibly also custom button and that they would act like buttons and not just images...

I would appreciate if someone could answer my question I've wanted to know how to do this for so long but haven't found a single way to do this...

I think it's possible, I hope I'm not wrong...
