[Qt-interest] Developing for multiple platforms (os)?

[Knapp]

Hi, I am looking at a project that needs to run on Linux, MS (all
forms) and Apple. Are there any pitfalls to watch out for? Does it
take a lot of work to make sure it works cross platform or can I just
write it to work on my Linux machine and know it will work fine on all
the others?
Thanks for any advice or insights!
