By a user interface..i think you mean this
Create a form that has buttons that open all the forms you want the user to access (button wizard is easiest)
This will be your 'main' form.
I would reccommend that you remove the scroll bars and record selectors (from properties = no) and in the case of forms that need looinf through records make your own buttons. remember that on each form you open to have a e.g. 'back' button (which simply closes the form) to make sure your not left with lots of open forms. Play with colours and picture buttons. Remember validations and control stop user error. so try to restrict the users control on each form (e.g. if you wan the user to open a form and only view one record remove the record selectors)..it always looks neater if you have your own record selector buttons anyway..they take a minute to make in button wizard. Try to set your 'on open' function (in properties) to a macro (really simple one..'maximise' so the user can only view the form your giving them the permission too.
