  I agree with you on dillo and iceweasel. Dillo doesn't support Java or PHP,
and any of the other browsers are just too slow.
I'm working on something similar, which requires local and remote UI.
I'm using apache and PHP for the webserver for remote UI and I'm
using FLTK for the local UI.  I've got high regards for FLTK. It was
relatively easy to get running on the board. There are not nearly the number of
package dependencies of GTK or some of the others, and the learning curve is
not bad.

wxPython is already in the repository and I've already run a small application using it.

Most of my apps have an embedded webserver and use AJAX to send data to/from the browser UI.  This makes it very simple to have both a local and a remote interface by just running a web browser on the appropriate machine.  I've only found one problem on the 7390 and that is Iceweasel doesn't run well enough to provide a responsive interface and Dillo doesn't support CSS or _javascript_.  I can either use wxWidgets or wxPython to create an interface but if I want a remote interface as well, then I have to maintain two UI's.

(I assume here you mean how your application runs, and not what tools
*you* use as a programmer). It depends completely on the target
{audience, function} of your program & embedded board.

If you need a complex GUI, to present graphical or image data, etc,
then by all means go for the X environment. If your target system is
an embedded control system, reacting to pushbuttons, doing PID
calculations, reducing A/D data, etc, then I'd stay away from a Xorg,
as it's just another layer of complexity and learning curves.

But, realize that:
* The number of Xorg-equipped embedded boards (of any manufacturer) is
a very minute percentage of the population,
* Most Xorg programming today is done with toolkits like Qt, etc.
Some toolkits (WxPython for example), make GUI programming
embarrassingly simple, but getting the toolkit ported to your target
board could be a lot of work.
* Eclipse is a graphical IDE for development, not a GUI toolkit for
the target system.

I'd suggest you start with standard POSIX programming, and graduate to
GUI systems as you see a need.

One other approach (again depending on your target), would be to
interact with your app via http ....
