I see. Try this, then:

<row>
	<column>
		<stretch/>
		<radio>...</radio>
		<stretch/>
	</column>
	<column>
		<stretch/>
		<input ... />
		<stretch/>
	</column>
</row>

By "program", are you referring to your plugin, or to an external application? 
If the data is shipped with your plugin, I suggest to package your plugin as 
an R add-on package (see 
http://rkward.sourceforge.net/documents/devel/plugins/external_plugins.html). 
Place your data in the "inst" subdirectory along with the RKWard specific files. 
Now you can query R (>= 2.13.0) for the path to your package installation 
directory using path.package(). This does not give you access to the path in 
JavaScript, though. Don't know, whether that is a hard requirement.

If the data is shipped with an external application, are you sure that will 
always be installed in the same path as RKWard? If so, you could query R for 
that path using
   Sys.getenv ("RKWARD_ENSURE_PREFIX")
or
   system ("kde4-config --prefix")
.

However, if there is any chance that the path might vary, then please take a 
look at the following wishlist item:
   http://sourceforge.net/tracker/?func=detail&aid=3448066&group_id=50231&atid=459010
? Does this match what you are looking for? Feel free to add comments to that, 
of course.

Regards
Thomas
