I am sure you know about PCI and when you say " base address of pci card ", you are probably referring to BARx (BAR0) value.

You can go to MSDN and find explanation of PCI for windows, guidelines on writing a driver as well as sample drivers.

If you haven't done windows driver development using WDK already then this is not going to be a simple task.

You may also want to have a look at Jungo's WinDriver and similar softwares that do major part of giving you access to the bus and detecting youe device and then can just concentrate on programming your device.

Some specific links
If you want to program through WDM directly, then you may start here

You may prefer to use WDF (A wrapper on WDM that handles most of the common functionality among different drivers). A generic sampe for that is
