Matt, if "my program" in this context is an original work where Michele is
the copyright owner and which is not derived from GPL code, then
I think his question may be about dual licensing of his original code,
not the (L)GPL libraries. In that case, the answer for dual licensing
GPL/proprietary of Michele's original code would be "probably yes."

I am not a lawyer.  Michele, you need a real lawyer for
these questions.
