The first option would be a pure Pascal one, driving either a graphical 
or a text-based (curses etc.) UI. However in practice I think you'll 
find that the majority in here who have any interest in GUI support use 

I tend to use the FPC+Lazarus combination on (Debian) Linux targeting 
x86 (including -64), SPARC, PPC and sometimes ARM, MIPS is also getting 
there slowly. Sometimes also x86 Windows and SPARC Solaris, and other 
people regularly target OSX etc. There is a bit of a problem in that all 
of us tend to test the less popular combinations somewhat sporadically, 
and at present some of these really do require careful choice of 
compiler version and- if using Lazarus- widget set.

fpGUI and MSEgui definitely have their good points, they're lean and are 
only mean in self-defence :-)
