wxWidgets lets developers create applications for Win32, Mac OS X, GTK+, X11, Motif, WinCE, and more using one codebase. It can be used from languages such as C++, Python, Perl, and C#/.NET. Unlike other cross- platform toolkits, wxWidgets applications look and feel native. This is because wxWidgets uses the platform's own native controls rather than emulating them. This package is built with the '--disable-gui' flag, which requires GTK1 or GTK2. If you need it for that purpose, then you need to track down those gtk dependencies.
