I think you just need to learn more about Gnu Radio, GRC, and perhaps 
software-development methodologies in general.

If you describe in more detail what it is you're trying to do, there are 
others on this list who may have gone down that road before, or will
  recognize similarities.

But I'll say this again, without meaning any offence to anyone.  SDR/DSP 
very often is a deeply-technical thing.  Without sufficient knowledge
  in a number of disciplines, including RF and analog system design, 
digital-signal processing, real-time software development, operating systems
  concepts and systems engineering,  and software development 
methodologies in general, progress on any particular project is likely 
to be slow
  and sometimes painful.

GRC/Gnu Radio are great tools, as are other, similar, tools, like 
SimuLink and so on.  But success isn't just about the tools, it's about 
the experience of the
  person wielding the tools.   The discuss-gnuradio mailing list is a 
diverse place, but it cannot be a substitute for education/experience in 
some of
  the disciplines that aren't really directly related to host-based 
digital signal processing, but are absolutely necessary to be successful.
