Back in the 1990s, IBM (or rather a small spin-off from IBM) developed a
product that included the the sort of thing you're thinking of. Certainly
the programmer didn't have to do anything to get access to controls on a
dialog.
First, the dialog was not based on .rc files - they turned out to be
inadequate for the purpose. Rather a format using a pre-cursor of XML was
used to define the dialogs - a bit like Microsoft's XAML (see
http://en.wikipedia.org/wiki/Extensible_Application_Markup_Language). There
was also a visual layout tool that produced the "XML".
Essentially, a dialog was invoked by the middleware and responsed to
invocations about user actions on the dialog. Here's a code fragnmebt from a
"dfialog" to illustrate (Rexx was a supported language):
when NwiMethod( "Notify" ) then do
/* This message is sent to me whenever the user does something */
/* to the window for which I am the View Object. */
name = SdsGet(hData, "Name", 1) /* Name of Control */
code = SdsGet(hData, "Code", 1) /* Action on Control */
select
when name = "Apply" then do
/* Update requested, so invoke Model-View Update framework: */
mrc = NwiSelf("UpdateModel")
if mrc = 0 then
crc = NwiCtl("Message", "Set", "Text", "Order Placed OK")
else
crc = NwiCtl("Message", "Set", "Text", "Error - Try Again")
return
end
when name = "Refreshview" then do
/* Refresh View requested, so invoke the Model-View */
/* Refresh framework: */
a = NwiSuper("Refresh")
return
end
when name = "Clear" then do
/* Clear message area requested, so clear it (set to blank): */
crc = NwiCtl("Message", "Set", "Text", " ")
return
end
otherwise nop
end
Mind you, providing the infrastructure code for this required several
man-years of C programming.

None that I know of.
