What kind of idl?
Is it COM interfaces?

In principal, you should find out how these libs are generally linked against, then use that method with your Qt application.
Qt applications are normal c++ apps!

The .idl files are the API files for a video capture card that i have and want to write a application to, i have written a simple program for it in c++ in Ubuntu but now i want to use it on windows and need to rewrite it some, in Linux the library files came as a .h file that i just included but for windows it came as a .idl file and i can't find out how to use it.

Do you have the library binary for windows?

IDL's are just interface definition, without the actual working code in a lib, or source code that you can compile you can't use them. (to my knowledge)
