There is a free executable version you can download and use, but the source is not free, sorry.
Actually i have compiled Logic Gui some time ago on a mac, but the user interface and MaxGui for the mac was too different that it worked nice. I hope that the new MaxGuiEx will make at least the code more cross platform so i can give it a second try.
Nevertheless users of Logic Gui have reported that they used it also for creating mac forms, the source can be used for any platform of course. If i remember correctly even running Logic Gui in Parallels has worked, which makes the data exchange may a bit easier.
