And some are also "calling compatible", have a look at
texconfig-dialog. IIRC: dialog, kdialog and gdialog have a common
basic interface (e.g. the same "yesno" option). So you can often do a
test for X ($DISPLAY or more reliably a specific test[1]), set a
variable $DIALOG accordingly to "dialog" or e.g. "kdialog" and the
just use

    $DIALOG --yesno "You want fries with that?" 5 30

(just tested the above with $DIALOG being dialog, kdialog and gdialog :)

[1] I've a self-written "Xruns" that tests if X is actually running
    and not whether just "DISPLAY" is set.

        disp = XOpenDisplay(NULL);

    I use it for several stuff, in above context, I'd use:

    if Xruns; then
        DIALOG="gdialog"
    else
        DIALOG="dialog"
    fi
    ...
    $DIALOG --yesno ...
