I'd say that depends on the program and what it is expected to do. 

And, BTW, we're almost there in a lot of respects: Swing's layout 
managers and Xserver manage most of what's needed here, apart from their 
use of pixel counts to set the size of displayed objects. I accept that 
this is most unlikely to change but would like to point out that if the 
sizes of said displayed objects were given in fractions of the screen or 
containing window size, then programs using them would be even more 
portable than they are at present.
