I'm afraid this is a typical newcomer idea. (Along with building your own 
Ada compiler or an Ada operating system.) As someone who has managed a 
project to create an Ada "toolkit" (Claw), I can certainly say that it seems 
many times easier than it appears. Moreover, it is really simple to make 
fundemental design decisions that makes it much harder to create and/or use 
than necessary (and usually it is too much work to change them, as you'll 
only find out the consequences after it gets into significant usage). And 
then, if people actually start using your toolkit, then you'll have another 
problem of trying to upgrade it without breaking compatibility. This sort of 
thing is not for the faint-of-heart, and rarely leads anywhere but a lot of 
effort wasted.
