The GTK bindings it uses are pretty low level overall -- e.g. dealing with ManagedPtr's and whatnot. You could probably make it nicer and easier to read, at least, if you spent some time wrapping a few of those UI bindings with a couple data types and helpers, made it a little nicer, etc. Overall there's going to be some unavoidable "setup gunk" though. You could make some of the code nicer, but the application is pretty small. For such a small little thing, I think abstracting away any further might end up in too much fluff, anyway.
