Not really they wrote software for Macs and decided to make a version that ran on the PC in order to sell iTunes products.
They did make AppleWorks 5 run on a PC used to have both versions on the CD.
If you knew anything about computers, you would know that Intel processors are different than the processors in the Mac at the time. They had to rewrite it to support the Intel machine code. Making "a version that ran on the PC" is the same as writing software for the PC. I've written machine code since the 1970s, and different CPUs use different instruction sets, not to mention whether it supported 8, 16, 32, or 64 bit architecture. You can't just port over a program unless it is emulated and it is therefore crippled.
They also made Filemaker for Windows before spinning it off as a separate company. In the past, they made QuickTime and Safari for Windows, which were made obsolete by better alternatives (like Chrome, which uses the same WebKit engine as Safari). They are still supporting iTunes, iCloud, and Bonjour, and Windows drivers for Apple hardware (required to make Boot Camp work).
