Reusing Audacity Source Code

I would like to ask if anyone can successfully use the Audacity source code in their own program? I am trying to reuse the Audacity signal playback, recording, and display function, but I don’t know how to do it due to its connection with wxwidgets. I have in mind several concepts: 1. Compile all Audacity as a dll and call it in my C # program (is this possible?) 2. Extract the functions for playing, recording and displaying the waveform and compile them into dlls that will be used in my C # program. Please advise. Thank.
