What Tuning?

ANY tuning is possible on a ukulele as long as the ukulele's construction supports the required string tension and a string is available . The manufacture or the builder of the ukulele would or should have this string tension information. The string manufacture typically has the tension information for their strings on their respective web sites.

There are three common tunings in popular use today, C, D and G tuning — with C tuning being the most popular.

Re-entrant Ukulele Tuning?

If coming from the guitar world where the strings, tuned low to high, is often called a linear tuning. An instrument like the ukulele with a higher pitched string four is called a re-entrant tuning where the lowest note of the instrument might not be the lowest string. This can seem a little strange at first. The re-entrant tuning, places all the notes of a chord within one octave, is part of the unique ukulele sound. This tuning is especially common for the smaller soprano and concert ukuleles.

Tuning is one of the aspects of the ukulele that gives it its charm. Or, it's a plot by builders and manufacture to have you buy more ukuleles.

Here is a great article on tuning systems by Richard Sleigh.
