It could be a good learning exercise.

But its not a waste of time if you learn valuable skills from it. 
*Somebody* has the write and maintain the low-level stuff, and if we all 
did nothing but use the high-level libraries, who would maintain them?

I'm reminded of the situation in scientific computing, where there are 
many important libraries written in Fortran which nobody can maintain 
because nobody understands how they work.

Asad: show us the code you've started with. You are far more likely to 
get a useful response to *concrete* questions about a specific problem, 
than a vague "show me what to do" general question.
