I'm working on a couple of personal project to improve my Perl skills. Among other things they need to provide a GUI interface on different OSes. In the past what little GUI work I did on Perl used TK (and that was just working through some sample projects). I know that beyond TK, Qt and GTK are also options.
Are there others?
Among the available options, what do you recommend for this purpose. Right now I'm leaning towards GTK as an Ubuntu user but I'm wondering if Qt might not be a better choice for cross platform work with Windows.
