Just thought I'd add this for the record.....
As a general strategy for building GUIs for use in R, I believe it
will be much more beneficial to do this in two steps:
a) create a set of R-language bindings to the GUI toolkit
of interest (Qt in this case)
b) build one or more GUIs for R in the R language.
The obvious benefits are that i) we can use the bindings to write
other GUIs, and ii) more people can adapt the GUI code to create their
own customized version(s). This hopefully avoids us creating "the" R
GUI containing an interface to every function known to mankind! A
third benefit is that perhaps the GUI design can be more readily
adapted for different toolkits (e.g. Gtk, Qt, wxWindows, MFC, etc.)
To toss in my $.02--it seems to me that it would be nice to push the GUIs (or any interface) "out of the core" s.t. GUIs are basically creating an R context just like any other embedding program. For most GUIs the main executable (if I understand Duncan's comments correctly) would mostly be a stub to get the GUI moving inside of the package that actually implements the GUI itself (allowing for more control over the GUI from the R environment---dynamic menus, etc, etc). Alternatively, there could be a generalized GUI interface whose C interface is implemented by the main executable and then registered (now that registration is nice)---this is probably the more difficult route and perhaps the more limiting route in the long run (various GUIs may have various nice features).
We already have bindings for several toolkits: the tcltk package to Tk, RGtk for Gtk/Gnome, (a recently more stable) SJava for Swing/AWT. The SWIG, the RGtk package, etc. might provide a place to look for automating the bindings to Qt. The KDE toolkit, Qt, is C++ which makes it slightly more tricky to handle. But there are C bindings for it.
Well, it could be an ObjC binding :-)
