Sure, take a look here :

http://sourceforge.net/project/showfiles.php?group_id=3D9863

and choose either wxX11 or wxMotif (for example).
Then you'll have to slightly modify wxt_gui.h and wxt_gui.cpp so that=20
those behave as wxGTK, i.e. replace

    #ifdef __WXGTK__
    ...
    #elif defined(__WXMSW__)
    ...
    #else
    # error "No implementation"
    #endif

by

    #if defined(__WXGTK__)||defined(__WXX11__)
    ...
    #elif defined(__WXMSW__)
    ...
    #else
    # error "No implementation"
    #endif

assuming you try with wxX11 (these conditional parts are there because=20
gnuplot on Windows already has its own main loop.

And finally you may have to comment the code related to the clipboard if=20
the compiler complains, as wxMotif or wxX11 are not supposed to support=20
it entirely according to http://wxwidgets.org/docs/supported.htm

Then, have fun !

Yes, this case is handled now. The macros PKG_CHECK_MODULES (provided by=20
pkg.m4 which is in gnuplot tree) check for the presence of pkg-config=20
and the configure script will just disable wxt if this program can't be=20
found. You can try. Just rename pkg-config temporarely and see.
