gb.db.mysql is not a good starting point, as it is not a component that 
declares classes, but that acts a "driver" for the gb.db component. Moreover, 
it a C component, not a C++ one.

I suggest starting from gb.pdf, which is a C++ component using a C++ shared 
library, with only a few classes.

Please look at it, and come back to tell me what you understood about class 
declaration.

And can you tell me which library you want to access, and give me more details 
about what your needs are? Because some interpreter special features may be 
needed or not, and your component could be part of Gambas.
