Of course we don't know what the requirements are. You may have a

suggestions.
Well said.
And, if choosing to do your own UI (I did this for my "math drills"
app for kids), be aware that the following can add quite a bit of
additional work:
- accessibility
- resolution independence
- potential need for IB palettes/plug-ins
These, and perhaps more I'm missing, are things you get for free
when using the standard UI.
Though you can get fairly simple "custom image" based buttons for free
with the standard UI. Just set the image and alternate image, set the
button to not be bordered, and set the behavior as desired (on/off,
highlight, etc...).
This will give you the accessibility, resolution independence, and IB
support automatically. Combine it with a custom window with an image
background and no title-bar and you can get a simple "custom UI" with
very little work.
Alternatively, you can work like Widgets do and use a WebKit view with
the appropriate set of images (especially if you use SVG based
images), JavaScript and CSS support to get a more complex custom UI
with a bit more work, but still get some of the "free" benefits (or at
least get those that web-pages have, such as resolution independence
and at least some accessibility).
Now as to how appropriate it is to make your own customized UI, that's
a different matter (though the general answer is "rarely, but there
are special cases").
