I've downloaded Open Watcom C/C++, and I'm having a bit of trouble....

1) I've no idea how to use the graphics library.
2) I want to call a DLL file, but I dunno how...(the help ennunciates on this pretty good, but you'd have to be a guru to understand)
3) Are Watcom's .LIB files the same as VC++'s .LIBs?

I was using MinGW(Dev-C++) but I switched to this, hoping for better.... er......... results. But all I've found is that most source/people don't support Watcom.... So along with these questions, should I even continue to use Watcom?
