File Finder in C

First of all Sorry for my bad English. I am not native English. I am going to write a program that list all available logical disk drives. Then ask the user to select a drive. then takes a file extension and searches that file type in given drive (including directories and sub-directories). Program should be able to run on windows xp and onward. It should be single stand alone application. I am not expert in C. I have some hands on C#. i have following questions in this regard. 1. Is there any IDE/Tool in which i can write C# like code that directly compiles to single stand alone application for windows? 2. Can you recommend some libs that i can use state forward for this purpose like using in C#? (I have seen dirent and studying it.)

I coppied some code that i am testing as a startup.
