When a tcode is created you can select which SAP GUI it has support for from HTML, Java and the main Windows GUI you are probably most familiar with.

SAPGUI for HTML
WF_EXTSRV does not support the HTML web based GUI. The SAP GUI for HTML generates HTML pages for each screen of the SAP transaction so that it can be executed within a standard web browser. Please note there are technical restrictions and possible incompatibility issues with certain browsers which means some transaction functionality may not function correctly.

SAPGUI for Java
WF_EXTSRV does not support the Java based GUI. The SAP GUI for Java support provides more controls than the SAP GUI for HTML, but requires a plug-in to be downloaded and installed on the users PC so is less popular than the SAP GUI for HTML.

SAPGUI for windows
WF_EXTSRV does not support the Windows based GUI. Windows(WinGUI) support is the most popular option and transactions can be run under SAP GUI for Windows.
