"Hello World" is a console type program and I believe that you can compile console programs with Borland C++ Builder.I wasn't aware that this isn't capable of building simple, non windos programs
I searched-around Borland's web site a little, and was able to confirm that version 5 could build console applications... I'll bet this feature is still in Builder 6.
Just to add to the confusion... "Hello World" compiled as a console application (with a windows compiler), will appear to be a DOS program when you run it on a Windows system, but the resulting 32 bit exe will not run under 16 bit true-DOS.
