Same here. I needed a CLI based RTTY decoder but could not get it done in GNU radio. It turned out to be easier to code this in C++ [1], though I had to learn a lot on the way. GNU radio has step learning curve...

Not quite what you are describing, but Universal Radio Hacker is a useful tool for reverse engineering protocols.
I just want a GUI tool which lets me take data streams, mix them, add them, run a function over them, preview them as a scope, power spectrum or IQ chart, play them through a speaker, decode them as mpeg, GPS signals, or anything else.
It seems GNU radio offers all that, but is so fiendishly hard to use it's easier just to write code in C to process my data as I want and plot it with matplotlib.
