Actually there are such things already in place in FR. These are 
genric services that can be used by any plugin. Therefore they are not 
associated with a particular but are rather published in the command 
section of the databus, more precisely in:
/system/ui/commands/App/Services/

There you'll find YesNoDialog, YesNoCancelDialog and MessageBox dialog.

Invoking one of those is quite easy .e.g for MessageBox
cmd_mgr = @plugin["/system/ui/commands"].manager
cmd_mgr.command('App/Services/MessageBox').invoke("File Load Error!",msg)

As to the GotoLine and GotoWord you mentioned they definitely relate 
to the EditPane plugin so they should appear under 
/system/ui/commands/EditPane where a number of EditPane related 
services are already published.

The editpane renderer plugin should publish be responsible for 
building the FX dialog box and display it as well as publishing it 
under /system/ui/commands/EditPane and retrieve the line number typed 
by the user.

The start method of the editpane plugin should publish a new item in 
the Edit Menu (e.g. Goto Line - Ctrl-G) and trigger the goto line 
dialog box

Hope this clarify how things are working in FR:

a) The UI and the application logic are decoupled
b) The services are published and invoked through the databus rather 
than called directly which makes the plugin architecture so powerful
