Hope this helps: 1) You can build your forms in windows or in Unix platform -- I mean the .fmb file. But if you will be deploying in the different platform, then you will have to copy all the libs and all. So it is advisable you build it in the same platform. In Unix you can use f60gen utility to create the .fmx. 2) You can create the pl/sql in vi editor and run it from sqlplus in unix. Alternately, you can use sqlnavigator or toad to build it in windows and even create the objects. Let me know if you need more help.
