Assuming you had the protocol - what would you do? It's a bit of work to do the windows front end for the debugger even if you use the open source stuff. For me, my time is precious so I'd rather pay a reasonable amount of money to someone for a solution rather than try to hack something together myself. Wouldn't you be better off spending your time writing your application and using more rudimentry means of debugging? Or don't put bugs in your code in the first place!!!!
