I can only assume he was talking about graphics in DOS. No mattter, that's hardly a prerequisite for windows programming! It can't hurt to give it a shot. If you like what you read in those tutorials I would say that you probably have the right kind of brain for it.
oh and the most simple windows program that I can think of is even easier than yours adrianxw
Code:
#include <windows.h>
int PASCAL WinMain(HANDLE hInstance,
HANDLE hPrevInstance,
LPSTR lpszCmdLine,
int nCmdShow)
{
MessageBox(NULL,"Hello World!","Even Simpler",MB_OK);
return 0;
}
