Probably. But the best way would be to use the library 
directly (both GUI and commndline version are only 
frontends to the library engine) - see httrack.c for 
example (most useful code is inside the main() function - 
the rest of the code is only here to display funny 
animations so that the user is not bored during a download)

But beware: HTTrack is *GPL* - it means that if you embed 
it in a project, or use its library, you *MUST* use GPL for 
the project too.
