guess I will have to learn the TCL C API like you mention and get it
done.

SWIG does its job very well. For a first approximation, you can probably just pass the headerfile into it like

swig -tcl8 -c++ headerfile.h


If you want a crisp tclish interface, you can improve the interface by writing proxy classes. Also exotic types can be integrated quite easy by providing a so called "typemap". With the typemap you can change the way SWIG interfaces TCL and C for specific function arguments. So you have the full control, but don't need to repeat tedious work. The only disadvantage may be some performance lost in comparison with a fully handwritten glue code.
