Here's one example:

  http://www.metamill.com/

It appears to be a successful shareware product, and the Linux version
uses GTK as you can see,

  $ ldd ./metamill
        libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0x40026000)
        libgdk-1.2.so.0 => /usr/lib/libgdk-1.2.so.0 (0x40181000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x401ba000)
        libm.so.6 => /lib/i686/libm.so.6 (0x40298000)
        libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
        libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x402ba000)
        libdl.so.2 => /lib/libdl.so.2 (0x402e0000)
        libgmodule-1.2.so.0 => /usr/lib/libgmodule-1.2.so.0 (0x402e4000)
        libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x402e7000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x402ef000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

GTK is LGPL as someone else mentioned, so as long as you don't 
statically link, you should be fine.
