My point is that it's not any less complicated than making a GUI-less VST. If the OP doesn't want to code VSTs at all, then Synthmaker is the better choice. It's really easy, you just put in a C or assembly module, click on it, and enter your code. It is rather expensive, though.
I think you'll find yourself rather constrained without going into C or C++. VST, LADSPA, CSound, etc. are all C or C++. Nyquist seems optimised towards fairly simple plugins without going into DSP code much. Also, VST plugins are much more universal than other standards. You might just want to bite the bullet and deal with the C++ junk to get coding. Low-level DSP is fun.
