I am in need of a very simple UI which just allow user to run 3 GCode programs with help of UI. user not required to know anything about plots or anything.

I am working on Raspberry pi 4B. I plan to use Glade.
While going through available tutorial I observed that I should have Glade-gtk2, but unable to find this for raspberry pi4B, so got the glade which ever available. Currently could install 3.38.2 version. I am able to open the UI, create sample UI screen using buttons what I need. 

I came across following problem. Kindly help

1) I couldn't find any document on how should I start running the gcode file on press of button. Where can I find the doc for same?
2) I tried running sample linuxcnc configs/sim/axis/gladevcp/gladevcp_panel.ini   But it failed with errors in attached file. Is it due to glade version? if so where can I find the Glade-GTK2

Do you want to use AXIS or doesn't it matter?
For example in GMOCCAPY you can define very simple macros which execute G-code:

It doesn't matter as i just want 3 buttons to be visible to user. User is not expected to know what how and so on...

The Python interface would probably supply what you need.

Looks like this will be the one helpful. But then i m not getting complete picture. I need to write python script and provide all required parameters for initialisation including ui then poll..

Any sample would be helpful.

you list of errors was not attached.
Gladevcp in master uses GLADE3 and python3

I take it you want to build a completely custom ui - not a panel attached to an existing screen.
Gladevcp or Qtvcp would be capable of this.

How will the user be expected to home machine - do they need to set an origin?

Sorry didn't observe that file didn't get attached.. Just added in original message.

I will provide a small GCode to bring the machine to home. So basically to move one gcode to allow movement in predefined manner. Then emergency stop and another gcode for bringing machine to home.

As you said gladevcp can be used, but I couldn't get it working as expected and I couldn't understand which command to use for running GCode.. I believe EMC Run should work.. but couldn't find details on how to pass an argument and how the HAL file is connected to this custom UI..

I would use the new gladevcp libraries to do this:
linuxcnc.org/docs/devel/html/gui/gladevcp-libraries.html
Should be more straight forward.
So a gladevcp panel with a few buttons that connect to a python handler file that calls the functions such as
ACTION.OPEN_PROGRAM()
ACTION.RUN()

Surely lots of details left out.

Again if it was I, i would develop this as a side panel on AXIS untill you get it to the point that you can do everything from the panel then use the panel directly instead of AXIS.
