Hello,

I'm wondering... If I take GPL'ed software in C and port it to Delphi with substantial re-writing during the process, do I have to release the result under GPL license?

Yes.

Can I study the software,
see how something is done,
delete the source off my computer,
and write a knock off and sell it under a new license?

Yes. :-)
