1. Syntax

The basics of building a simple gui is told by the links in gtkdialogDoc gtkdialog documentation. You should have played a bit with some examples before you continue.

About QUOTES ( " and ' )
To show content of a variable in the gtkdialog code, we need to quote the variable correctly inside the gtkdialog code.

TEXT='Hello world'

export script='
<text>
 <label>Content of variable is: '"$TEXT"'</label>
</text>'

gtkdialog --program=script

Now in other words - Because this is important!!!

First realize that you put all the gtkdialog code into a variable - ie MAIN_WINDOW or Psync:

export Psync="<window title=\"Psync\"...........</window>"

if you now try to echo Psync you'll get

<window title="Psync"...........</window>

which is correct code. But if you used ' instead of ", like this:

export Psync='<window title=\"Psync\"...........</window>'

you'll get

<window title=\"Psync\"...........</window>

This will give a syntax error, while

export Psync='<window title="Psync"...........</window>'

will give correct syntax.

Now using a variable inside the gtkdialog code like this:

TITLE=Psync

export Psync="<window title=\"$TITLE\"...........</window>"

returns

<window title="Psync"...........</window>

while

export Psync='<window title="$TITLE"...........</window>'

returns

<window title="$TITLE"...........</window>

and not the content of variable TITLE

Now return to the first example about quotes. This example combines the use of ' and ".
