Graphical User Interface Support Script is really a language for operating a computer, rather than programming one, so we cannot do this via X11 libraries. The example uses leafpad for our open window, and the box symbols to enclose our text:
<lang guiss>Start,Programs,Applications,Editors,Leafpad,Textbox,▼
<lang guiss>▼
▲Start,Programs,Applications,Editors,Leafpad,Textbox,
Type:[openbox]Hello World[pling][closebox]</lang>
