Beginners idea, is it possile

[kemeris]

Hi guys,

I know this forum not for beginners, but still keeping my faith to find some answers here.
All I want to know, is it possible to accomplish my idea and realize the scale of such a project.

So my idea:

As I am not sure I can call it "OS", I will call it just "program".

My program should act as "layer" (virtual device) between one specific PCI sound card and Windows OS on one x86 or x64 machine.
Windows should treat this virtual device as PCI device, while not been able to access real PCI sound card directly.
My program should process data (at driver level) coming from windows to virtual device and then passthrough to real PCI device.
My program should be isolated to prevent any possibility for windows to modify process instructions used in my program.
Program should be as simple as possible without involving visualization if possible.

I know this is rough description without any technical specifications and I will understand if answer will be "this is complete absurdity".
And sorry for my poor English, its my third language
Best regards

I have no idea how windows work but yeah it sounds like all of it could be possible except for the "My program should be isolated to prevent any possibility for windows to modify process instructions used in my program." part.
